Mounting

The RFRB – RF Room Thermostat should be mounted 1.5 meters above the floor level on the wall where the heating is to be controlled. The place of installation should be chosen so that the sensor can measure the room temperature as accurately as possible. It can be fitted to recessed conduit boxes, surface mounting boxes, directly on walls or table mounting with stand provided. Product Usage Instructions Prior to setting the thermostat, it is necessary to complete allrequired settings described in the factory default settings and specifications & wiring sections.

CAUTION! Before commencing any work on the electrical connections, you must first disconnect the device from the mains. None of the 230V connections must be live until the installation has been completed and the housing is closed. Only qualified electricians or authorized service staff are permitted toopen the terminal box. There are parts that carry mains voltage behind the cover.
