Thermostat Subbases
INSTALLATION INSTRUCTIONS
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.
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.

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.
— 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.

3. Remove the subbase from the wall and drill two
3/16 inch holes in the wall (if drywall) as marked. For
firmer material such as plaster or wood, drill two
7/32 inch holes. Gently tap anchors (provided) into
the drilled holes until flush with the wall.
4. Position the subbase over the holes, pulling wires
through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.

WIRING
T
All wiring must comply with local electrical codes and
ordinances. Refer to Fig. 9 through 15 for typical
hookups. A letter code is located near each terminal for
identification.

Disconnect power before wiring to prevent
electrical shock or equipment damage.
1. Loosen the terminal screws on the back of the
thermostat and connect the system wires. See
Fig. 8.

IMPORTANT
Use 18 gauge, color-coded thermostat cable for
proper wiring.
Subbase Installation
2. Securely tighten each terminal screw.
3. Push excess wire back into the hole.
4. Plug the hole with nonflammable insulation to
prevent drafts from affecting the thermostat.
The subbase can be mounted horizontally on the wall or
a 2 in. x 4 in. wiring box. Position the subbase horizontally on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the subbase (for appearance
only). The thermostat will function properly even
when not level.
2. Use a pencil to mark the mounting holes. See Fig. 7.
