Heating and Cooling Modes
The thermostat is pre-set for heating operation (HEAT). You can manually change the operating
mode between AUTO, HEAT, COOL, OFF, and, for heat pump applications with auxiliary heat,
EMERG.
Press the RIGHT TAB button on the home screen to view this
screen.
Use the SCROLL buttons to select the desired operating mode.
Press SELECT to engage the operating mode.
AUTO: The thermostat automatically selects heating or cooling depending on the indoor
temperature.
HEAT: The thermostat controls only the heating system.
COOL: The thermostat controls only the cooling system.
OFF: Heating and cooling systems are off.
EMERG: Note: only for heat pumps with auxiliary heat. The thermostat only controls the
Emergency (Auxiliary) heat which leaves the heat pump’s compressor locked out.
Use this setting only when you suspect the heat pump is out of service or the
outdoor conditions render inefficient the operation of the heat pump.
