2.7 Room Unit
-
QAA 55
•
The room unit should be located in the main living room while giving consideration to the following points:
•
The place of installation should be chosen so that the sensor can capture the room temperature as accu-
rately as possible without getting adversely affected by direct solar radiation or other heat or refrigeration
sources (about 1.5 meters above the floor)
•
In the case of wall mounting, there must be sufficient clearance above the unit, enabling it to be fitted and
removed
When the unit is removed from its base, power is
cut off so that the unit is out of operation.
