pump or conventional heating and cooling systems.
Select models have terminals for light emitting diodes
LEDs, remote temperature sensors and remote setback
timer. The LED models  have up to two field configurable
LEDs and up to two factory assigned LEDs. Refer to
Table 1. All Q7100 Thermostat Subbases require a
common wire to the supply power.

Location

Subbase without Remote-Mounted Temperature Sensor

Install the subbase about 5 ft (1.5m) above the floor in an
area with good air circulation at average temperature.
See Fig. 1.

Do not install the subbase where it can be affected by:

drafts, or dead spots behind doors and in corners.

hot or cold air from ducts.

radiant heat from sun or appliances.

concealed pipes and chimneys.

unheated (uncooled) areas such as an outside wall
behind the thermostat.

Subbase with Remote-Mounted Temperature Sensor(s)

Install the subbase 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. 1.

Do not mount the sensor(s) where it can be affected by:

drafts, or dead spots behind doors and in corners.

hot or cold air from ducts.

radiant heat from sun or appliances.
