The innovative Ratio®-room temperature sensor RTF103 by Omnio is an effective battery and maintenance free radio bus system for building automation.
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.
