Summary of Contents

• Page 1: Operating instructions for the RFRB - RF room thermostat include important sections on factory default settings, specifications and wiring, mounting, installation, button and symbol descriptions, resetting the thermostat, on/off function, and lock function. Before commencing any work on electrical connections, disconnect the device from the mains. Only qualified electricians or authorized service staff are permitted to open the terminal box. The thermostat should be wall mounted at a height of 1.5 meters above floor level in the room where heating is to be controlled. Insert the batteries into the thermostat and choose the installation location to ensure accurate temperature measurement. Press the reset button on the PCB to reset the thermostat, confirming the setting by rotating the hand wheel. The paired zone of the programmer must be in specific states for the on/off function to operate correctly. The thermostat can be fitted to recessed conduit boxes, surface mounting boxes, directly on walls, or table mounting with the provided stand. Ensure the wireless enabled programmer is installed at least 1 meter away from metallic objects and other electronic devices. Keep this document for reference prior to setting the thermostat.
• Page 2: Operating instructions for the RFRB - RF room thermostat include a lock function. To lock the thermostat, press the hand wheel for 10 seconds until the lock symbol appears. To unlock, press the hand wheel for 10 seconds again until the lock symbol disappears. Connecting the RF thermostat with the programmer involves lowering the cover on the front of the timeswitch and moving the selector switch to the RUN position.
