Install room units in the main occupancy rooms. 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 metres above the floor)
The base provides the power for QAA55 and QAA75. When the units are removed
from their base, power is cut off (i.e. the units are out of operation).
