APPLICATION
The Q7100 Thermostat Subbases provide electronic
control of commercial 24 Vac single or multistage heat
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.

INSTALLATION INSTRUCTIONS
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions
to check out the product operation.
CAUTION
Disconnect power supply to prevent electrical
shock or equipment damage.
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.
RECYCLING NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do
control in the trash.
Contact your local waste management authority
for instructions regarding recycling and the proper
disposal of the old 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.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall
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. See Fig. 2
through 6.
