2.1 Wired components
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 meters above the
floor)
The base provides the power for QAA55 and QAA75. When the units are removed
from the base, power is cut off (i.e. the units are out of operation).
