Planning
@
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 accurately 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.
