Thermostat mounting
Align the 4 tabs on the wallplate with slots on the back of the thermostat, then push gently until the thermostat snaps in place.
Push excess wire back into the wall opening.
Plug wall opening with non-flammable insulation.
Installer setup
Follow the procedure below to configure the thermostat to match the installed heating/cooling system, and customize feature operation as desired.

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 the 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): This 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.
