Auto Changeover (heat/cool)
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.
Press until screen
displays “Auto”
Note: The Auto system setting
may not appear, depending on
how your thermostat was
installed.

Built-in compressor protection
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 display will flash
the message Cool On (or Heat On if you
have a heat pump).When the safe wait time
has elapsed, the message stops flashing and
the compressor turns on.
Message flashes until safe
restart time has elapsed
