• Page 16: Installation guide 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. Built-in compressor protection helps prevent damage to the compressor in your air conditioning or heat pump system. Damage can occur if the compressor is restarted 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 will flash on the display. Systems with heat pumps can be set to operate in one of two ways: Comfort Setting or Economy Setting.
