Q7100A,C
Thermostat Subbases
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
LED, remote temperature sensors and a remote setback
timer. The LED models have one or two field configurable
LED and one or two factory assigned LED. Refer to Table
1. All Q7100 Thermostat Subbases require a common
wire to the supply power.
Table 1. Q7100 Subbases.
a
Depends on the model.
RECYCLING NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do
not
place your old
control in the trash.
Contact your local waste management authority
for instructions regarding recycling and the proper
disposal of the old thermostat.
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow

your application.
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions
to check out the product operation.
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power supply before installation.
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.
— 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.

Subbase Installation
The subbase can be mounted horizontally on the wall or
a 2 in. x 4 in. wiring box. Position the subbase horizon-
tally on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the subbase (for appearance
only). The thermostat functions properly even when
not level.
2. Use a pencil to mark the mounting holes. See Fig. 7.

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 the mounting screws.

WIRING
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.
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power supply before installation.
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.
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.
