  • Page 10: Operating The Thermostat

    OPERATING THE THERMOSTAT Setting the temperatures for heating and cooling Your thermostat is installed with the heating set at 68° F and the cooling set at 72° F. You can use these or change them so your home is as warm or as cool as you would like it to be.

  • Page 11: Using The Fan

    OPERATING THE THERMOSTAT Using the fan When the fan is on, it helps distribute air throughout your home for a more even temperature in all spaces. You can set the thermostat so that the fan runs only during your heating and cooling cycles (auto mode) or to run continuously. The thermostat is set at the factory to run automatically as needed.

  • Page 12: Using Emergency Heat (Heat Pump Systems Only)

    OPERATING THE THERMOSTAT Using emergency heat (heat pump systems only) Emergency heat is useful when the automatic auxiliary heat system can’t keep up with demand. (Systems with heat pumps use “auxiliary heat” when it’s too cold outside for the heat pump to heat the house without help. The display indicator for this is aux heat on.) If the heat pump compressor that works with auxiliary heat fails, or if the heat pump isn’t working at all, you can turn on the emergency heat for that extra help.

    OPERATING THE THERMOSTAT Installing or replacing the batteries You can install batteries in your thermostat so that if the power goes out, the display will still show the indoor temperature.

  • Page 23: There Is A Power Outage

    WHAT IF . . .
