Bottomless power generation comes from ambient sources such as linear motion, light and temperature differentials. Wires run through buildings like veins run through our bodies. Wires are pervasive and vital to day-to-day operations; however, today’s brave new ‘green’ world warrants consideration for solutions that reach beyond the confines of wires. As one decade comes to a close, EnOcean asserts that the next decade will feature wireless and batteryless controls that will carry building energy initiatives where wires fall short.

Widespread Smart Building integration has been stalled by installation costs and ominous tasks such as pulling wires through walls and ceilings. Battery-dependent wireless solutions can overcome some installation barriers, but the market has indicated it will not tolerate the maintenance issues tied to them. If the goal is to reduce energy consumption and CO2 emissions, then integrators need non-invasive installation means and payback data that tips the scale in favor of spending the money to modernize existing buildings. Now that more than 100,000 buildings have been fitted with EnOcean-based products and energy reductions are in the books, a case is being made that wireless energy harvesting controls provide a radically easy form of Smart Building integration.

The Power of Unused Energy

The hallmark of the EnOcean wireless standard is batteryless and wireless communications. The technology stems from a simple observation – where sensors capture measured values, the energy state is constantly changing. For example, when a switch is pressed; temperatures and luminance levels change. These rudimentary operations generate enough energy to transmit radio signals that automate lighting and HVAC control. Instead of batteries or line power, EnOcean uses miniaturized energy converters and capacitors that power sensors and switches. EnOcean’s bottomless power generation comes from ambient sources such as linear motion, light and temperature differentials.

Energy harvesting enables the generation of radio signals from extremely small amounts of energy. Using just 50 micro watts of harvested power, an EnOcean-based control can transmit a radio signal 1,000 feet (150 feet is typically indoors – through walls and ceilings). An important part of the patented secret is using short signal durations – the entire radio transmission process starts, executes and completes in less than one thousandth of a second.

3rd Generation Wireless Energy Harvesting

EnOcean recently released its 3rd generation suite of energy harvesting wireless modules. The modules are based upon the Dolphin ASIC, the world’s first platform that supports self-powered two-way wireless communications, ultra low power sleep modes and the ability to self-power actuators such as water valves and air vents. Wireless building automation devices spend much of their time asleep; so EnOcean engineered the lowest sleep current in the industry (200 nA). Dolphin-based modules consume approximately 1/10th the power of common low power radio modules. The platform allows OEMs to create energy-autonomous controls that are able to draw power from multiple ambient sources, such as solar, linear motion and thermal energies.

EnOcean modules are often referred to as ‘application modules’ and these modules ship out-of-the-box with extensive firmware functionalities built-in – such as basic switching, dimming, measuring, etc. – and can go straight into an application without additional programming. EnOcean developed highly efficient methods of synchronizing sensors, supporting RF acknowledgments as well as integrated sensing/control functions. Application-specific functions reduce product development times and are embedded in each module; however, integrators can now also develop their own firmware using EnOcean’s new Dolphin Studio – support software for custom firmware development, RF packet monitoring and C-based code sampling.

The new Dolphin platform conforms to the open, interoperable EnOcean Alliance protocol and enables manufacturers to rapidly develop solutions to suit today’s ‘green’ economy. EnOcean’s Dolphin system architecture is also backward compatible with earlier EnOcean products and installations. In addition to the introduction of new platform, the company has also further enhanced wireless capabilities with remote commissioning and wireless routing creating new opportunities previously not possible with energy harvesting. Dolphin-based radio modules are now available direct from EnOcean or through and its distribution channels.

HVAC Energy Management

Radio waves are in the thick of the race to make buildings more energy efficient. Integrators can reduce installation costs and recoup those installations costs via energy usage reductions over time. Older buildings are often guilty of wasting giant sums of power. The Government estimates that 80% of buildings constructed prior to 1980 are energy-inefficient and do not house and Smart Building Technology. Additionally, older buildings often have little or inadequate insulation.

Speedy Implementation

Entire installation can be carried out with minimum interruption – Virtually impossible to achieve using a cabled solution because of the need to break open walls (duct work and cabling). Implementation of the system in even a large office complex can take just one week — including installation of the central control engineering to monitor and govern energy consumption. The biggest challenge is the right positioning of the room sensors because you’re dealing with thick walls made of concrete and steel. However, choosing EnOcean’s self-powered wireless technology can save up to 20 percent in installation costs alone and significant energy savings.

Lighting Energy Management

Buildings account for 38% of this country’s CO2 emission and lighting accounts for 40% of the energy consumed by buildings. Buildings therefore present an important place to start improving energy management via things like occupancy-based lighting control systems. Occupancy Sensors have been identified as the primary means for conserving energy.

Installation

Because the controls do not require wiring or batteries, installation can be completed in just three steps.

1. Replace existing light switches with line-powered receiver light switches (wiring is the same as a standard switch).
2. Program the light switch receiver to respond to occupancy sensor and self-powered light switch. The devices are factory set to manual-ON, auto-OFF (custom to suit California Title 24) – no extra setup was necessary; however, an “auto-ON, auto-OFF” mode is also supported.
3. Mount sensors and light switch – anywhere! Since they are self-powered and wireless, the controls were mounted according to building owner preferences.

The EnOcean Alliance

More than 120 automation solution manufacturers formed the EnOcean Alliance to promote sustainable buildings via batteryless and wireless controls. The Alliance is committed to interoperability through 1 wireless standard. Collectively, Alliance members have manufactured 300+ building automation products that are on the shelf today – more than any other wireless standard.

Interoperability is an important key to the Alliance’s success:

• Between Products – All EnOcean-based sensors and switches are interoperable – regardless of the manufacturer. For example, an occupancy sensor manufactured by Vendor A can communicate to a controller manufactured by Vendor Z.
• Between Applications – EnOcean-based solutions support multiple applications (ie. a single wireless light switch can communicate to lighting systems as well as HVAC systems).
• As Gateways & Interfaces (LonMark, BACnet, DMX, 802.11, TCP/IP Ethernet, KNX, RS-232/485 Serial, etc.)

OK, at Ivory Egg we could be viewed as a little KNX or DALI biased, so I promise to be as objective as possible and open to feedback here. At the end of the day we are independent, simply want to deliver the best solutions to our clients and I would hope this article, at the very least, will stimulate some form of debate. You can view the complete thread at AV Forums.

So, in terms of the players (at least who I perceive to be the market ‘leaders’ in this field), and again you may disagree with my selection, I have decided to look at the following solutions. This selection is based purely on the names I come across on a weekly basis:

• KNX
  KNX is a standardised (EN 50090,ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus).
• Crestron
  Crestron is the world’s leading manufacturer of advanced control and automation systems. They offer integrated solutions to control audio, video, computer, IP and environmental systems, and streamline technology to improve the quality of life for people in corporate boardrooms, conference rooms, classrooms, auditoriums, and in their homes.
• Lutron
  Lutron Electronics Company, Inc. is a privately held corporation that designs, manufactures, and sells lighting control systems and a variety of other related products. Its probably fair to say that Lutron lead the way in lighting control systems.
• Rako
  Rako provide state of the art digital dimming technology. Their innovative solutions meet the needs of a diverse range of applications by offering lighting systems that are simple to use, creative, easily installed and cost effective.
• DALI
  The Digital Addressable Lighting Interface (DALI) is a digital protocol for the controlling of lighting in buildings, such as electrical ballasts and dimmers.
• INSTEON
  INSTEON technology is a dual-band mesh topology employing AC-power lines and a radio-frequency (RF) protocol to communicate with and automate home electronic devices and appliances, which normally work independently. It is a home automation networking technology invented by SmartLabs, Inc., and was developed based on the X10 model for control and sensing applications in the home.

Not everybody active in this field, but a good starting point? Unfortunatley though, we have a bit of a problem when trying to compare these so-called competitors, as basically what we’re dealing with is a mix of different standards, manufactures and solutions that are all competing against each other. I would love to be in position to just compare like for like and publish the pros and cons of each, answer the questions in places such as AV Forum, but that would not provide a true representation of each solution (I hope I’m not stating the obvious here)…

For example, it makes sense on some projects to have a mix of KNX and DALI. As DALI is an open protocol for lighting control mainly in commercial buildings, while the growth area in KNX is for residential and LED. Take Heathrow Terminal 5, which has a KNX backbone with switches/PIRs etc and a gateway to DALI for the lighting. KNX can’t compete with DALI, as the DALI is fitted to the ballasts that control the lighting and sit in the actual light fitting. They are complimentary systems and we approach it from that point of view as we sell KNX/EIB DALI gateways at Ivory Egg.

In terms of KNX vs. some of the other systems, well Lutron is bar far the market leader in terms of pure lighting control. Rako on the other hand sell purely wireless lighting controls and they are great for DIY/retro-fit. As for INSTEON, which is again a wireless control technology, they currently have no European devices so it doesn’t really complete with KNX and is more of a competitor to the likes of Z-wave and EnOcean (which is another blog altogether). And finally  we have Crestron, who supply more AV & generic device control solutions.

It is worth pointing out that Crestron do provide a complete AV, lighting and control solution. It does it by controlling different devices from multiple manufactures and a wide range of different protocols via a central controller. From a consumer point of view Crestron is “Interface Centric” via tablet and in wall touch screens. This hides the complexity of using Lutron for lighting, X manufacturer for heating and Z for multi room audio. It is an expensive route to take, but on the positive side it is highly configurable.

KNX is standard based and developed from a consumer point of view. It is switch centric, in other words it is a compact and stylish intelligent switch on the wall that can easily control the ‘functions’ in a room (HVAC, lighting, blinds etc). KNX has 1,000s of products that are certified to work together, but this is not the case with Creston. That said most consumers wouldn’t know the difference, as most simply go on look and feel, and that is where market leaders such as Basalte and Gira score highly. Their products are innovative, look fantastic on the wall and at Ivory Egg we can supply a whole host of fittings for 13amp sockets that will coordinate with the wall switches. And to be fair, this is what the architects are demanding!

So difficult to draw conclusions really. I guess the big question I’ve not really answered is what are they main differences between Lutron and KNX? As Lutron is a central processor based with proprietary technology and KNX is a component/manufacturer open standard, does that mean the KNX open standard is the lowest common denominator (as claimed by Lutron) or does that mean you get vastly increased flexibility (as claimed by KNX)? Is Lutron only lighting control – on/off/dim or is it full integration. If KNX gives you full integration, then why would you even consider Lutron? All very valid questions…

Yes, KNX provides a holistic approach to efficient energy usage. It is not limited to lighting or heating or metering or appliances or AV or any other specific function for that matter. The KNX platform has been adopted by many highly respected major manufacturers with their vast choice of products covering all these product lines. In the longer term, this is also important to building owners, as any installation is future proofed for any changes/upgrades that could be needed. As KNX covers such a diversity of applications using one standard, it means cabling networks can be much more simplistic and single twisted pair cabling can often suffice, with multiple elements all operating together on a single network. As I’ve already mentioned briefly with DALI, a number of the KNX manufacturers have also developed ‘gateways’ to other control protocols. These simple devices are used to expand the capability of KNX control systems to provide the complete solution for a building.

KNX has also worked closely with management-level protocols such as BACnet to enable a close co-operation between these two standards when the project requires additional integration. Every KNX-compliant piece of equipment is fully tested and certified to this highly stringent standard by an independent regulatory body – It is only at this point that it can carry the KNX logo, as controlled by the international KNX Association of Brussels. Therefore there is total confidence in reliability and interoperability, whatever KNX devices are chosen. In the UK we have a growing network of integrators who have joined KNX UK to share their experiences and to help promote the standard. They can also assist consultants as well as building owners in achieving the optimum solution for their building and with KNX also accepted throughout the world (and with partnership agreements with more than 30.000 partners in more than 75 countries worldwide) from China to the United States as well as Australia and the Middle East, it truly is a worldwide standard.

Lutron on the other hand is recognised as the leading brand in terms of pure lighting control, and rightly so… It has many advantages and is easy to install, retrofitable and extremely reliable. Their systems are a proven, extensively implemented technology that offers 2-way communication, is scene capable and can dim any type of dimmable lighting. All this is backed by an industry leading company with a very long history and their systems are available in a large number of styles and finishes, all backed with a 7 year warrantee. Plus they too can integrate window/shade controls and offer relatively easy intregration with Crestron and other control systems. However, while I find it hard to criticize KNX (and again, I can hold my hands up and say yes we’re a little biased), to me there are some obvious disadvantages to Lutron. For one it only controls up to 32 lights (expandable to 64). Then there is the fact it has no dedicated processor, so it relies on an automation processor. In other words if this processor fails, then I’m afraid you have to manually override or you have no lights at all. However, the ‘biggie’  (in my experience anyway) is that expansion always seems more complicated than it needs to be and is certainly more expensive than with KNX products.

The choice of lighting control is a wide one one I’m afraid, the above is only our humble opinion.  To be honest, what you really need to do is decide what functionality you want and then see what systems can support your needs. Its important you select an installer that can advise you on the systems that you’re interested in. Price is always important, but do not make it the main point, and you need to always be thinking about upgrades/adding to the system in the future. Also think about who can you get to do changes and tweaks to the lighting control system (these things are never right first time and commercial clients and their staff especially can be very demanding)?Does the control system intergrate with other manurfacturers you may be using and don’t be afraid to ask for them to show you existing installations they’ve completed that are using the products you’re interested in. KNX is certainly the logical choice to me in terms of flexibility and meeting demand, especially if you need to integrate other systems such as heating, blinds, AV etc, but always keep an open mind and one eye on what each of these systems can deliver.

Their fully bi-directional script allows easy control of each individual zones or dynamic group control with up to five user programmable group scenarios. Each zone has individual sound control (Bass/Treble, Loudness On/Off, Start/Max. Volume and Balance) which is stored within the Adagio® system and remains stored even after a loss of power. Furthermore, iPhone/iPod touch integration is also already built in and works with the free Crestron App available in the Apple App-Store.

There’s no need to program the Crestron system in any way since a pre-programmed macro is installed on the Crestron Adagio® system and ALL of the programming can be done in real-time on any Pronto. Estimated set-up time for a standard 6-zone system is less than 1 hour, which is quite remarkable! A 36 zone system can be programmed within 2-3 hours! That’s why they call it Easy and Fast then! All of their communication is solely via Ethernet and allows multiple users to access the Adagio® system simultaneously, with full bi-directional feed-back on ALL devices (even the iPhone/iPod touch!).

Full KNX/EIB integration is also included (although additional hardware is needed)… All you need is the empure KNiX-Port or iKNiX-Port and you can control each zone bi-directionally with any KNX/EIB switch.

Gira has recently expanded their range of glass Esprit frames with an additional design known as glass C. The soft edges and rounded corners of glass C offer a new alternative in the otherwise clearly-cut and linear switch range. The edges of the 6 mm thick glass frame are ground to a semi-circular form with the so-called ‘C grinding process’.

Gira has also added a black glass to the frame variants that corresponds perfectly with the architectural, linear design of the switch and lends Gira Esprit its particularly elegant character. The high-gloss surface of black glass has a distinctive depth and achieves an optical perfection that cannot be achieved with any other material or any other colour. The glossy black surface gives Gira Esprit an expressive presence that nevertheless blends unobtrusively into the surroundings. The range is especially well-suited for use within architecture with a high aesthetic claim, for example with open masonry, exposed concrete and glass. But also in combination with natural materials such as wood and natural stone or on brighter surfaces the black switches of Gira can create an exciting accent.

The switch inserts and covers are in aluminium, which further emphasise the impression of modern functionalism, harmonizing perfectly with the cover frame of black glass. Inserts and covers are also available in anthracite as well as matt pure white and glossy pure white. More than 230 functions from System 55 can be combined with the Gira Esprit cover frame, including Gira’s door communication system.

Recent meetings between the two organizations have opened the door to the full integration of wireless EnOcean and wired BACnet-enabled technologies, with the result that an EnOcean interoperability proposal has been drafted for the BACnet committee meeting at AHR Expo in Orlando, Florida. BACnet – a data communication protocol for building automation and control networks is defined in the ANSI/ASHRAE Standard 135 – 2008 and also the international standard ISO 16484-5.

The working group’s current standardization efforts aim to ensure the interoperability of multiple EnOcean and BACnet solutions available today or in development, as well as future implementations. “The task at hand is to define common implementation rules for an EnOcean/BACnet gateway,” said Dave Robin, Chairman of the BACnet Technical Working Group. “This will entail a number of issues, including specifying the network topology and the BACnet/EnOcean objectives needed to define a single model so that all implementations will be interoperable.”

As the organization responsible for promoting the use of BACnet technologies for building automation, BACnet International sees this as a significant achievement. “The world has evolved towards a wired and wireless infrastructure, and it is a significant step to bridge these together with a standard mechanism for building automation suppliers and users,” said Andy McMillan, President of BACnet International and President/CEO of Teletrol Systems. He added, “In the IT world, wired and wireless interoperability has long since been accomplished. I am very happy to be involved in the effort to make this available for the building automation industry.”

Leveraging the strengths of both technologies will create long-term value by allowing the existing wired BACnet infrastructure to seamlessly add wireless devices for additional functionality and greater energy savings. “As a practical, wireless extension of BACnet solutions, EnOcean technology is ideal for lowering cost of ownership in retrofits and new buildings,” said Graham Martin, Chairman and CEO of EnOcean Alliance. “As a field-proven solution for the BACnet environment, many facilities have already successfully deployed wireless solutions in which EnOcean and BACnet technologies are interoperating to reduce installation and maintenance costs, along with providing energy savings beyond 30 percent.”

A number of EnOcean Alliance partners will be exhibiting a range of interoperable EnOcean wireless devices for the BACnet platform at AHR Expo (Orlando, FL, Jan 25-27), including Distech Controls, winner of an AHR Honorary Mention Award for this platform.

Niko has been developing switching ranges for decades. With a hard-earned reputation for innovation, the company has continued in this tradition with the introduction of a revolutionary new concept in switches – the truly invisible switch. The imaginatively named ‘Mysterious’ range from Niko goes beyond traditional switches and socket outlets. With Mysterious, Niko takes the first step towards imagining life without any of the ‘traditional’ switching material.

Mysterious is a range of switches and sockets with an elegant and simple design that can be seamlessly integrated into any wall. When fitted, the switch can then be papered over painted like the wall so that only an incredibly discreet round edge remains visible. In the dark this outer edge lights up with the warm white glow of an LED that is incorporated into the switch. Mysterious simply adapts itself to the colour of the wall, just like a chameleon.

The switch is multi-functional, with its programme comprising push-buttons with one to four key points, sockets for data/TV connection boxes, and orientation lighting. The design is inspired to allow functionality into carefully designed interiors without detracting from the look of the room. Its an Architects/Interior Designer dream… No more ugly switches ruining their clean design aesthetic.

With more than 11,000 submissions from 61 countries, the international red dot design award is the largest and most renowned design competition in the world. It is divided into the red dot award: product design, the red dot award: communication design and the red dot award: design concept. Niko’s Mysterious was awarded the prestigious red dot award: product design.

Each year an international jury reviews and evaluates the submitted products according to criteria such as degree of innovation, functionality and the formal quality. This ensures the seriousness of the competition and its international acceptance. The group of jurors is made up of renowned designers and design experts from all over the world who reach their decisions on which designs are good enough to receive a red dot award independently and impartially. The constellation changes from year to year and guarantees a high degree of objectivity and reliability.

The award is as a seal of quality; it stands for membership of the best in design and business. After 90 years, its good to see that Niko continues to play at the top of its game and to lead the field.

Flush-mounted actuators are used with decentral KNX/EIB installations or in KNX/EIB compound installations (DRA, flush-mounted). They are allotted space in flush-mounted boxes or in cable conduits and utilise the existing power cables. In this way cable material is saved and fire load in buildings is significantly reduced.

Existing installations can be expanded more simply to KNX/EIB with flush-mounted actuators – in addition to the existing 230 V supply – only a bus line is required for operation of the actuators.

Zero-voltage contacts can be connected to the binary inputs and they can carry out various functions independently of one another or as a ‘block’. The functions of the binary inputs are identical for all actuators, other attributes however are configured at the factory in order to make the operation possible without the need for programming.

The flush-mounted actuator is connected to the 230 V supply via a flexible cable, approx. 20 cm in length. The connection of the binary inputs and the KNX/EIB is made via a 6-wire connection cable, approx. 30 cm in length. This can be extended to a maximum of 5 m.

Two auxiliary unit inputs (or three inputs with window actuators, blind actuators and heating actuators) are for on-site operation via conventional switches or buttons, or can be freely used as binary inputs for zero-voltage contacts (with applied bus voltage).

Window actuator

The window actuator combines a blind actuator with a heating actuator. It has three binary inputs with which in delivery state the connected blind or shutter can be controlled.

Functions of inputs

Functions of switching inputs: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction).

Dimming: Single and double-surface operation, time between dimming and switching and dim-step size can be set, telegram repetition and stop-telegram transmission possible blind: Command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step – Move – Step or Move – Step), time between step and moving mode can be set, slat adjustment time can be set.

Value transmitter and light scene auxiliary unit: Edge (push button as NO contact, push button as NC contact, switch) and value with edge can be configured, value adjustment with push button by pressing and holding button for value transmitters possible, light scene auxiliary unit with memory function and saving of the scene without previously calling up is possible.

• Blocker for blocking individual inputs
• Behaviour when the bus voltage returns can be configured separately for each input
• Telegram rate limiting

Blind output

• Behaviour after bus voltage failure and return can be set
• Separately parameterisable movement times with movement time extension for movements into the upper end position
• Feedback of the curtain position or slat position – Active or passive (object can be read out) cyclical feedback functions
• Feedback can be delayed until after the return of bus voltage
• Assignments to up to 5 different safety functions (3 wind alarms, 1 rain alarm, 1 frost alarm), or with cyclical monitoring
• Forced setting function can be realised for each blind output

• Status feedback (1bit or 1byte) automatically or on read request
• Valve control (open/closed while deenergised) can be configured
• Summer or winter operation can be selected via an object
• Cyclical monitoring of the corrected variable; if a corrected variable telegram remains off within a monitoring period, the output switches into emergency mode and an alarm message is sent
• The output can be locked in a forced position, and different values are possible for summer and winter operation
• Behaviour when the bus voltage returns and fails can be configured separately for each output
• Overload or short-circuit message via an object can be set
• Control of valve drives with switching operation or PWM operation
• Protective function for locked valve

Technical data

• Rated voltage: AC 230 V/50 Hz
• Connected load of blind output: switching current AC1: 3 A, motors: 600 VA
• Connected load of heating output: contact type: Triac, switching current 5 to 25 mA, drives per output: max. 2
• Number of inputs: 3
• Protection type: IP 20
• Temperature range: – 5 °C to + 45 °C
• Dimensions: 51 × 48 × 28 mm (L × B × H)
• Load line connection: with enclosed spring plug-in terminal
• Installation: flush-mounted wall box (Gira recommend the electronics box from Kaiser)

Installation

The actuators are installed flush-mounted in a wall box (electronics box from Kaiser recommended). Sufficient insulation must be provided between the 230 V cable and the bus or auxiliary units. The minimal distance between bus/auxiliary unit wires and 230 V wires is 4 mm.

Heating actuator

The heating actuator is used for switching electrothermic valve drives for heating systems. It has two binary inputs to which zero-voltage contacts can be connected for monitoring of a window contact for example.

Functions of inputs

Functions of switching inputs: two independent switching objects for each input present and can be enabled individually, command for rising or falling edge can be set independently (ON, OFF, CHANGE, no reaction).

Dimming: Single and double-surface operation, time between dimming and switching and dim-step size can be set, telegram repetition and stop-telegram transmission possible blind: Command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be configured (Step – Move – Step or Move – Step), time between step and moving mode can be set, slat adjustment time can be set.

About Gira

Gira places great value on product design. Through intensive cooperation with external and in-house design teams, Gira develop products, which are repeatedly recognized for their exceptional and simple design.

The modern electrical installation from Gira offers a broad range of intelligent building technology for convenience and security. Devices for networking home technology, music control for all rooms and comprehensive switch ranges, plus numerous functions for door communication, energy and light outdoors – and it all fits together. All functions and devices can be easily combined, and the uniform design lines always offer the right cover frame for every purpose.

The GiraShop.co.uk supplies the complete range of products that are currently available in the English language catalogue.

With this autonomous device it is possible to interconnect directly the internal system (building automation, industrial automation, BACnet, ModBus, Konnex…) to the external system (fire system, access control system, security system, HVAC, cold/warm generation, energy generation & measurement, lighting, hotel management, home automation…). A console RS232 port is also available to connect a laptop PC for programming and monitoring the device. IntesisBox® also offers the possibility to be connected to Ethernet/LAN/WAN networks expanding thus its possibilities with connection to ethernet/IP based protocol systems, remote monitoring, networks interconnection, web server, internet/e-mail alarm sending, SNMP…

Inside its internal structure, the IntesisBox® incorporates a high performance and reliability microcontroller with flash (non volatile) memory where the operating system and integration code (firmware) are saved. This internal structure, along with a watchdog system, ensures a suitable operation of the device every time, even when faced with power irregularities such as micro-cuts or longer power failures. It has no mechanical mobile components (fans, hard discs…), therefore reducing potential malfunctions and maintenance to almost zero, making this ideal device for industrial environments. It allows (depending on the model) the generation and register of datalogs associated to internal variables, useful for example to register historical data for temperature, relative humidity, etc. Thanks to an internal interchangeable lithium battery (with approx. 10 years life time), the internal historical data is stored in case of power failure. The firmware can be also updated via the console port.

IntesisBox® allows DIN rail mounting for easy installation inside an industrial cabinet and allows a wide range of input supply voltage, from 9 to 30VDC and also 24VAC, with a low power consumption of 1.4 watts. The operating temperature range is from -40°C to +70°C and the relative humidity from 5% to 95% (non condensing). It is not necessary to have any external RS232/RS485 converter, because IntesisBox® has RS485 port and can be directly connected to a RS485 bus. IntesisBox® can be also equipped with a Konnex TP1 (KNX/EIB) optocoupled port allowing to be directly connected to any KNX/EIB bus. All available IntesisBox® hardware versions are compliant with RoHS directive (2002/95/CE).

Along with the device, it also comes supplied (free of charge) with the LinkBox software, the software tool that’s needed for configuring and monitoring the IntesisBox®. LinkBox software runs on MS Windows® operating systems and uses a serial port to communicate to the IntesisBox®. It is possible to use LinkBox Software off-line (not connected to IntesisBox®) to configure the IntesisBox® more comfortably in the office and later download the configuration to the device using the serial connection in the field. Also supplied (again, free of charge) is a console cable that’s needed in order to configure the device.  This is a standard DB9 male to DB9 female cable.  Intesis can also supplied (on demand) an external plug-in power supply (european plug) 230VAC/12VDC 300mA to power the IntesisBox® if required.

The IntesisBox® is available to order now from KNXshop.co.uk in the Communication > Gateways/Convertors section.

Conventional electrical installations for lighting, shading, heating and security have reached their limits… As soon as the requirements exceed basic installation principles, installations using conventional technology become complex and expensive. The battery-free radio bus system Ratio® with EnOcean technology facilitates electrical installations, allows for a number of useful functions, increases comfort and security. It is environment-friendly and extremely economical.

The power generation is effected by transmission of roomlight into electrical energy from a solargenerator. It conduces to the measuring of the rooms temperature and the transmission by radio to the radio senders and actuators/gateways. By its very flat construction it can be installed on walls and even on glass. Short roomlight for the power generation means the temperature sensor can also be run with a battery.

The Ratio® switch actuators/receivers are activated by radio signals from the Ratio® radio senders. Each sender can actuate an indefinite number of actuators/receivers. The Ratio® radio senders have a fixed address and are programmed into Ratio® receivers (actuators). The Ratio® switch actuators activate various functions such as light bulbs, blinds, gates, doors, control valves etc.

Product & Function Description

The battery-free Ratio® temperature radio sensor is mounted on a wall and regulates temperature and air conditioning. It is used in combination with the receiver UPT and REGH or different gateways to connect to superordinate regulating systems. At each value change or in a 15 minutes interval, a radio signal (EnOcean standard) is sent that is received and analyzed by all Ratio® radio bus receivers. The Ratio® room temperature radio sensor is mounted to glass using adhesive or on walls, etc. using adhesive or screws.
