Option 16 - Maximum Cycles Per Hour Selections: 2, 4, or 6 -- Default is 4. The maximum cycle rate is limited by internal timers to the selected number of cycles per hour. You can use these or change them so your room is as warm or as cool as you would like it to be. To change the heating temperature, press the mode button on the left until the screen says heat. Press the up or down button located on the right side of the display until you reach the desired temperature.

Using the fan When the fan is on, it helps distribute air for a more even temperature in all spaces. You can set the thermostat so the fan runs continuously (on) or only 20 during your heating and cooling cycles (auto mode, sometimes known as cycle mode). The thermostat is set at the factory to run automatically as needed (auto). 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.
