Auto Changeover is a feature used in
climates where both air conditioning and
heating are used on the same day.When the
system is set to Auto, the thermostat
automatically selects heating or cooling
depending on the indoor temperature.
Heat and cool settings must be at least 3
degrees apart.The thermostat will automatically
adjust settings to maintain this 3-degree
separation (called “deadband”).
The 3-degree separation between heating
and cooling set temperatures is fixed, and
cannot be changed.

This feature helps prevent damage to the
compressor in your air conditioning or heat
pump system.
Damage can occur if the compressor is re-
started too soon after shutdown.This feature
forces the compressor to wait for a few
minutes before restarting.
During the wait time, the message Cool On
or Heat On (heat pumps only) will flash on
the display.When the safe wait time has
elapsed, the message stops flashing and the
compressor turns on.
Message flashes until safe
restart time has elapsed
Adaptive Intelligent Recovery
™
(Setup Function 13)
Adaptive Intelligent Recovery eliminates guesswork when setting your schedule. It
allows the thermostat to “learn” how long your furnace and air conditioner take to
reach the temperature you want.
Just set your program schedule to the time you want the house to reach your
desired temperature.The thermostat then turns on the heating or cooling at just the
right time to reach your scheduled temperature at your scheduled time.
For example: Set the Wake time to 6 am, and the temperature to 70°.The heat will
come on bef
ore 6 am, so the temperature is 70° by the time you wake at 6.
