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.

The KNX-compatible VARIA is an eight-channel display and controller with integral room thermostat that enables householders to take control of their environment in a living or workspace. With its sleek stainless steel buttons on a raised glass fascia, VARIA offers elegant styling with a rugged, long-lasting design that eliminates fragile touch screens.

It can display KNX-programmed profiles in as many as eight rooms, offering control over up to three functions in each of them that combine to provide the right ‘room scene’ for say reading, watching TV or sleeping. Scenes can be selected at the touch of a button, and users can adjust levels within limits defined at the time of installation.

VARIA can add an extra level of KNX intelligence and override these programmes, for instance, if ambient light levels suggest electric lighting is not needed, or presence detectors indicate that a room is unoccupied.

VARIA is available in the UK now from the Theben Group company Timeguard, a KNX UK member.
