—concealed pipes and chimneys.
—unheated (uncooled) areas such as an outside wall behind the thermostat.
T7200 Wallplate or Q7300 Subbase without Remote-Mounted 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.
Q7300 Subbase with Remote-Mounted Temperature Sensor(s)
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.
If multiple remote sensors are required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 3 through 8.
NOTES:
—When sensor averaging, the T7147A can be substituted for the T7047C. The T7147A includes OVERRIDE and WARMER/COOLER keys.

IMPORTANT
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.

NOTE: With the thermostat configured for a temperature averaging network (remote and internal sensing), the internal sensor has 50% authority of the averaged temperature.
Mounting Subbase/Wallplate
The subbase/wallplate mounts horizontally on the wall or a 2 in. by 4 in. wiring box. Position the subbase/wallplate horizontally on the wall or on a 2 in. by 4 in. wiring box.
1.Position and level the subbase/wallplate.
NOTE: A level wallplate is only for appearance. The thermostat functions properly when not level.
2.Use a pencil to mark the mounting holes. See Fig. 9.
3.Remove the subbase/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.
4.Position the subbase/wallplate over the holes, pulling wires through the wiring opening.
5.Loosely insert the mounting screws into the holes.
6.Tighten mounting screws.

SETTINGS
Using Thermostat Keys
The thermostat keys are used to:
•set current time and day,
•program times and setpoints for heating and cooling,
•override the program temperatures,
•display present setting,
•set system and fan operation,
•configure Installer Setup,
•check Installer System Test.
See Fig. 12 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 heat or cool.
—fan operates continuously in Occupied periods.
—fan is on continuously in Occupied periods and Unoccupied period recovery times.
Setting Temperature
Refer to Table 4 for the default temperature setpoints. See Programming section for complete instructions on changing the setpoints.
