Special functions
Auto Changeover (Setup Function 12): When set to Auto, the thermostat automatically
selects heating or cooling depending on the indoor temperature. The thermostat will
automatically adjust heat and cool settings to maintain a 3-degree separation (fixed).
Note: If you select Auto Changeover Only, the System Setting on the thermostat will stay
locked in the Auto position, preventing the user from changing it to Em Heat, Heat, Cool
or Off.
Adaptive Intelligent Recovery™ (Setup Function 13): Allows the thermostat to “learn” how
long the furnace and air conditioner take to reach programmed temperature settings, so
the temperature is reached at the scheduled time.
Compressor Protection (Setup Function 15): Forces the compressor to wait a few minutes
before restarting, to prevent damage. During the wait time, the message Cool On or Heat
On (heat pumps only) will flash on the display.
