Thermostat With Remote-Mounted
Temperature Sensor(s)
Install the thermostat in an area that is accessible for
setting and adjusting the temperature and settings.
Install the remote-mounted sensor(s) about 5 ft (1.5m)
above the floor in an area with good air circulation at
average temperature. See Fig. 4.
Do not mount the sensor(s) where it can be affected by:
— drafts or dead spots behind doors, in corners or under
cabinets.
— hot or cold air from ducts.
— radiant heat from the sun, fireplace, or appliances.
— concealed pipes and chimneys.

behind the thermostat.
If more than one remote sensor is required, they must be
arranged in a temperature averaging network consisting of
two, three, four, five, or nine sensors. Instal as shown in
Fig. 5-9.
