WALL THERMOSTAT
Avoid locations where the thermostat could be subject to
drafts from outside, or exposed to direct light from lamps,
sun, fireplaces, etc., or affected by air from a duct register
blowing directly on the thermostat.
The wall thermostat should be mounted approximately 5
feet from the floor. The preferred location is on an inside
wall situated in an area with good air circulation, and where
the temperature will be reasonably representative of other
living areas the thermostat is controlling.
