10.15 Room Unit Installation Procedure
1. Room unit location: The wall cradle should be located in the main living room while giving consideration to the following points:
The place of installation should be chosen such that the sensor can capture the room temperature as accurately as possible without getting adversely affected by
direct solar radiation or other heat or refrigeration sources (about 1.5 meters above the floor) (Fig. 45).
There must be sufficient clearance around the unit, enabling it to be fitted and removed.
Important : A TRV should not be fitted to the radiator in the same room as the room sensor.
If a TRV has been installed on this radiator, the TRV must remain set open at all times,
therwise the house holder will experience room temperature control problems.
