When nobody is present in the Temperature room, it would be a waste of energy to heat up the floor. In the EcoH or EcoO programs, the NRG-Temp is switching between the Reduced and the Comfort Temperature based on a weekly schedule.
±1,5 m Figure 3 If the NRG-Temp is mounted in a wall with a rough surface, e.g. bricks, use silicon glue to make a seal between the wall and the thermostat frame. Note: The NRG-Temp can also be mounted on a wall with a wall box.
Figure 4 3.2 MOUNTING THE FLOOR SENSOR The floor sensor should be installed in a separate flexible conduit for easy replacement and in order to avoid signal disturbance resulting in a possible malfunction of the thermostat. For best control performance, position the floor sensor between two heating cables as close as possible to the top floor surface.
3.3 CONNECTION OF THE THERMOSTAT TO THE POWER SUPPLY The thermostat must be connected to 230VAC according to the circuit diagrams (Figure 6). Direct connection – e.g. single heating circuit Heating cable Power supply Pilot wire Floor 230 VAC 230 VAC signal sensor Max.13A...
