SETTINGS
System and Fan Settings
System settings control the thermostat operation as follows:
Em. Heat (Q7100C only): Emergency heat relay is
automatically controlled by the thermostat. The cooling
system is off. The compressor is de-energized.
Heat: The thermostat controls the heating.
Off: Both the heating and cooling are off.
Cool: The thermostat controls the cooling.
Auto: The 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.
See Fig. 11.
NOTE: Always press the keys with your fingertip or similar
blunt tool. Sharp instruments like a pen or pencil
point can damage the keyboard.
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 present setting. To change between heat and
cool, press the Information i key until the setting to be
changed appears. Press the increase ▲ or decrease ▼ key to
adjust the setting.
Override Temperature Settings
(Select Models)
The T7100 temperature settings can be overridden in three
ways:
— Using the Override key (T7100F only), acting as a toggle.
— Using a remote setback timer.
— Using an occupancy sensor.
The temperature settings change based on the Installer
Setup 27.
NOTE: The Installer Setup 27 is factory set at zero degrees
so this setting must be changed for the temperature
to change.
The Override key temporarily changes the current
temperature to a preset offset. The remote timer and
occupancy sensor opens (temporary setpoint) or closes
(comfort setpoint) contacts according to the setting.
See Table 5.
