or Heat Pump Thermostat
INSTALLATION INSTRUCTIONS
APPLICATION
The T7100F Microelectronic Thermostat provides electronic control of 24 Vac commercial single zone heating, ventilating and air conditioning (HVAC) equipment. It is designed for use with the Q7100A Subbases for conventional heat/cool applications and the Q7100C Subbases for heat pump applications. The T7100F is field configurable for automatic or manual changeover between heating and cooling. All T7100F Thermostats require a common wire to supply power.
NOTE: When Q7100C Subbases are used, Installer
Setup Option must be set to 01 (heat pump).
RECYCLING NOTICE
If this control is replacing a control that contains mercury in a sealed tube, do control in the trash.
Contact your local waste management authority for instructions on recycling and the proper disposal of the old thermostat.

INSTALLATION
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 ratings given in instructions and on product to
make sure 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.
Mounting and Wiring Q7100 Subbase
Refer to the subbase installation instructions for mounting and wiring information.
Setting Keypad Lockout Switch
The T7100F can be configured for keypad lockout to prevent changes to the temperature or system settings. DIP switch number 1, on the back of the thermostat, activates the lockout feature. See Fig. 1. The DIP switch must be set to the ON position (up) to activate the lockout feature. The factory setting is off (down). Be sure to set the switch before mounting the thermostat on the subbase. When the DIP switch is set to the ON position it disables all of the keys on the thermostat.

Using Thermostat Keys
The thermostat keys are used to:
• Set temperature,
•Display present setting,
• Configure Installer Setup,
• Check Self-Test.
Select models have keys to:
• Temporarily override the temperature,
• Set the system operation,
• Set the fan operation.
See Fig. 3 for key information.

SETTINGS
System and Fan Settings
System settings control the thermostat operation as follows:
Em Heat (Q7100C only): 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 operation, depending on the
indoor temperature.
Fan settings control the system fan as follows:
On: Fan operates continuously. Auto: Equipment controls fan.
The system default setting is Heat and the Fan default setting is Auto. Use the keys to change to the desired settings.
Temperature Settings
The default setpoint for heat is 70°F (21°C) and for cool is 78°F (25.5°C). Press the increase or decrease key to change the setting. To change between heat and cool settings, press the Information i key until the setting to be changed appears.
Override Temperature Settings (Select Models)
The T7100 temperature settings can be overridden in three ways: — Using the T7100 Override key, acting as a toggle. — Using a remote setback timer. — Using an occupancy sensor.
The temperature settings change based on Installer Setup 27.
NOTE: Installer Setup 27 is factory set at zero degrees
so this setting must be changed for the tempera­ture to change.
The Override key changes the current temperature temporarily to a preset offset. The remote timer and occupancy sensor open (temporary setpoint) or close (comfort setpoint) contacts according to the settings. See Table 1.
Always check the display to determine if the thermostat is controlling the comfort, temporary or remote setpoints. Temporary is displayed when the Override key is pressed or the occupancy sensor or remote setback timer is energized.

INSTALLER SETUP
NOTE: For most applications, the thermostat factory
settings do not need to be changed. Review the factory settings in Table 2 and if no changes are necessary go to the Installer Self-Test section.
The Installer Setup is used to customize the thermostat to specific systems. Some of the options include temperature display, remote sensing system, changeover, minimum equipment On time and minimum Off time. Installer modes are listed in numerical order in Table 2. It includes all the configuration options and the factory-settings available for the T7100F.
IMPORTANT
The Installer Setup must be set correctly for the HVAC equipment, thermostat and subbase to operate properly.
A combination of key presses are required to use the Installer Setup feature: — To enter the Installer Setup mode, press and hold the
Information i key with the increase and decrease keys until the first mode number is displayed. All display segments appear for approximately three seconds before the first mode number is displayed. See Fig. 4 and 5.
— To advance to the next Installer Setup mode, press
the Information i key.
— To change a setting, use the increase or decrease
key.
— To exit the Installer Setup mode, press and hold the
Information i key until the display returns to normal (approximately three seconds). The display scrolls the mode numbers backward to get to the normal display. The Installer Setup mode is automatically exited if no key presses are made for five minutes.
