Thermostat Setup Menus
The thermostat must be set up for the correct HVAC system type for proper operation.
Preset HVAC System settings
The thermostat is preset for the following typical HVAC system configuration:
•
HVAC system type:
Standard gas/electric
•
HVAC fan type:
Gas heat
•
HVAC heating stages:
One
•
HVAC cooling stages:
One
If the thermostat is installed on this type HVAC system, the System Setup does not need to be
changed.
If installed on a Heat Pump HVAC system or any HVAC configuration other than the preset settings,
change the settings in the SYSTEM setup menu to match the HVAC system.
Note:
To conserve energy, the thermostat backlight turns off after a short time of no activity. The
first button touch turns on the backlight (but does not initiate any action). Touch the button again
to initiate the action desired. If the backlight is already on, button touches work with the first touch.
Wait Mode
The thermostat has a
Minimum Off Time
(MOT) delay after any heating or cooling cycle ends. This
delay prevents rapid heating/cooling cycles and also provides “short cycle protection” for the system
compressor. This delay may be noticeable when you change a setpoint, and it does not respond
immediately due to the MOT delay timer preventing the system from restarting. The MOT delay time
can be adjusted in the Advanced Settings menu of the thermostat, but there is a minimum of five
minutes delay to assure compressor protection.
Minimum Run Time (MRT)
The thermostat has a
Minimum Run Time
delay after the start of any heating or cooling call. This
minimum run time assures even heating and cooling cycles. The MRT will keep the system on, even if
it reaches the setpoint room temperature or if you change the setpoint to a temperature that would
satisfy the call until the MRT expires. The MRT can be adjusted in the Advanced Settings menu of the
thermostat.
Note:
The MRT delays are shown by flashing heat or cool icons on the display.
Frost Protection
The thermostat has a frost protection feature built in. It forces the highest possible heat stage to turn
on in order to prevent room temperature from becoming too cold. Once enabled, frost protection
activates automatically at 41°F (5 °C) and deactivates at 48 °F (8 °C), regardless of System Mode and
Heat/Cool Set Point. To activate the feature, go to Advanced Systems Settings Menu (p17).
