INSTALLATION
Q7300 Subbase with Remote-Mounted
Temperature Sensor(s)
When Installing this Product…
1. Read these instructions carefully. Failure to follow the
instructions can damage the product or cause a
hazardous condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions to
check out the product operation.
If only the remote-mounted temperature sensor(s) is used to
sense and control room temperature, then install the
thermostat in an area that is accessible for setting and
adjusting the temperature and settings.
If both the subbase and remote-mounted temperature
sensor(s) are used to sense and control room temperature,
then install the subbase about 5 ft above the floor in an area
with good air circulation.
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. 2.
Location
T7200 Wallplate or Q7300 Subbase without RemoteMounted Temperature Sensor
Install the thermostat about 5 ft (1.5m) above the floor in an
area with good air circulation at average temperature. See
Fig. 2.
Do not install the thermostat 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.
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
If more than one remote sensor are required, they must be
arranged in a temperature averaging network consisting of
two, three, four, five or nine sensors. See Fig. 3 through 7.
NOTES:
— When sensor averaging, the T7147A can be substituted
— Up to four T7147As can be used in parallel to place the

IMPORT ANT
To avoid electrical interference, which can cause
erratic performances, keep wiring runs as short as
possible and do not run thermostat wires adjacent to
the line voltage electrical distribution systems. Use
shielded cable (Belden type 8762 or equivalent for
2-wire and Belden type 8772 or equivalent for 3-wire).
The cable shield must be grounded only at the
controlled equipment case.

Mounting Subbase or Wallplate
The subbase or wallplate mounts horizontally on the wall or a
2 in. x 4 in. wiring box. Position the subbase or wallplate
horizontally on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the subbase or wallplate (for
appearance only). The thermostat functions properly
even when not level.
2. Use a pencil to mark the mounting holes. See Fig. 8.

3. Remove the subbase or wallplate 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.

1. Loosen the terminal screws on the subbase or wallplate
and connect the system wires. See Fig. 9.
IMPORTANT
Use 18-gauge, solid-conductor color-coded
thermostat cable for proper wiring. If using
18- gauge stranded wire, no more than ten wires
can be used. Do not use larger than 18-gauge wire.

Mounting Thermostat on Subbase or
Wallplate
The thermostat mounts on the subbase or wallplate after they
are installed.
1. Engage the tabs at the top of the thermostat and
subbase or wallplate. See Fig. 10.
2. Press the lower edge of the case to latch.
NOTE: To remove the thermostat from the wall, first pull out
at the bottom of the thermostat; then remove the top.
A. ENGAGE TABS AT TOP OF THERMOSTAT AND SUBBASE OR WALLPLATE.
See Fig. 11 for key information.
Setting System and Fan (select models)
The system default setting is Heat. The fan default is set so
the fan operates continuously in Occupied periods,
Unoccupied period recovery times and with the heating and
cooling equipment in Unoccupied periods. Use the System
and Fan keys to change the settings. Fan and system
operation are configured in the Installer Setup options.
The system settings are:
Em Heat (T7200E, T7300/Q7300C,D,H): Emergency heat
relay is on continuously. Thermostat cycles highest stage
of heat. Cooling system is off. Compressor is de-energized.
Heat: Thermostat controls the heating.
Off: Both the heating and cooling are off.
Cool: Thermostat controls the cooling.
Auto: Thermostat automatically changes between heating
and cooling depending on the indoor temperature.
The fan settings are:
On: Fan operates continuously in occupied period.
Auto: Equipment controls the fan in the Unoccupied
periods. The Intelligent Fan™ operation (Installer Setup
number 17) offers three choices for the fan operation in
Occupied periods:
— fan turns on only when there is a call for heating or
cooling.
— fan operates continuously in Occupied periods.
— fan is on continuously in Occupied periods and
Unoccupied period recovery times.

equipment damage caused by the system running
without the fan.
NOTE: Be sure to set the thermostat time after exiting the
Installer Setup.
Installer Setup numbers are listed in Table 8.
IMPORTANT
Only configurable numbers are shown on the device.
Example: If the thermostat does not have a system
