Thermostat Setup Menus
The thermostat must be setup for the correct HVAC system type for proper opera on.
Preset HVAC System se
ƫ
ngs
The thermostat is preset for the following typical HVAC system con
fi
gura on:
• HVAC system type: Standard gas/electric
• HVAC fan type: Gas heat
• HVAC hea ng 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 con
fi
gura on other than the preset se ngs,
change the se ngs in the SYSTEM setup menu to match the HVAC system.
NOTE:
To conserve ba ery life, the thermostat backlight turns o
ff
a er a short me of no ac vity.
The
fi
rst press of any bu on turns on the backlight (but does not ini ate any ac on). Press the bu on
again to ini ate the ac on desired. If the backlight is already on, bu on presses work with the
fi
rst
press.
Wait Mode
The thermostat has a Minimum O
ff
Time (MOT) delay a er any hea ng or cooling cycle ends. This
delay prevents rapid hea ng/cooling cycles and also provides “short cycle protec on” for the system
compressor. This delay may be no ceable when you change a setpoint and it does not respond
immediately due to the MOT delay mer preven ng the system from restar ng. The MOT delay me
can be adjusted in the Advanced Se ngs menu of the thermostat but there is a minimum of
fi
ve
minutes delay to assure compressor protec on.
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time delay a er the start of any hea ng or cooling call. This
minimum run me assures even hea ng and cooling cycles. The MRT will keep the system on, even
if it reaches the setpoint room temperature, or you change the setpoint to a temperature that would
sa sfy the call, un l the MRT expires. Changing the Mode to OFF will cancel the MRT and the system
will turn o
ff
immediately. The MRT can be adjusted in the Advanced Se ngs menu of the thermostat.
NOTE:
The MRT delays are shown by
fl
ashing heat or cool icons on the display.
