Honeywell Evohome Relay Unit

The Honeywell Evohome BDR91 is a wirelessly controlled relay unit designed for switching heat sources within the Honeywell Evohome smart heating system. It acts as an intermediary between the EvoTouch control unit and the heat source - when the EvoTouch sends a request to switch on, the BDR91 unit wirelessly receives the signal and activates the connected source. This makes the heating operation fully automated and adapted to the current needs of the household. The device uses wireless RF communication at 868 MHz with a range of up to 30 meters in a residential building. This eliminates complicated cable routing and makes installation quick and economical. The relay unit is powered directly from the 230 V mains and is equipped with a switching contact suitable for voltages of 24...230 V and loads up to 5 A. The Honeywell Evohome BDR91 is a reliable and important part of the whole system, which facilitates heating control and contributes to greater energy efficiency in the home.
