The Q7100 Thermostat Subbases provide electronic control of commercial 24 Vac single or multistage heat pumps or conventional heating and cooling systems. Select models have terminals for light-emitting diode LEDs, remote temperature sensors, and remote setback timers. 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.

When Installing this Product…
CAUTION
Disconnect power supply to prevent electrical shock or equipment damage.
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:
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 an average temperature. See Fig. 1.
Do not mount the sensor(s) where it can be affected by:
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.
The sub base can be mounted horizontally on the wall or in 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.
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
Disconnect power before wiring to prevent electrical shock or equipment damage.
Fig. 14. Typical hookup of Q7100C1008 in a two-stage heat and two-stage cool heat pump system.
Includes remote temperature sensor and remote setback timer.
Fig. 15. Typical hookup of Q7100C1073 in a three-stage heat and one-stage cool heat pump system.
Includes remote temperature sensor and remote setback timer.
Mount the thermostat on the subbase after the subbase is installed.
