9.1 Positioning Thermostats
A room thermostat should be mounted on a
vibration-free wall or column at a height of
approximately 5' (1.5 m) from the floor to measure
the ambient temperature. It should be clear of both
cold drafts and the direct path of warm air from the
heater.
Avoid mounting thermostat on outside walls or in
areas directly exposed to radiant heat or sunlight.
