Using emergency heat (heat pump units only)

Emergency heat is useful when the automatic auxiliary heat system can’t keep up with demand. (Units with heat pumps use “auxiliary heat” when it’s too cold outside for the heat pump to heat the space. The display indicator for this is aux heat on.)

Here’s how to set your thermostat to use emergency heat.

1.Press the mode button repeatedly until you see Em heat in the upper left of the display.

2.To turn off emergency heat, press the mode button again to select heat, cool or off.

Turn the unit off

To use the thermostat to turn off the heating and cooling system, press the mode button on the left repeatedly until the display shows off in the upper left.
