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

auxiliary 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. (You’ll know there’s a problem if the house can’t seem to

get warm when it’s very cold outside.) You want to avoid using emergency

heat, though, because it’s the most expensive option. And, of course,

if you suspect a problem with your heat pump, call your heating and

cooling dealer immediately.

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

1. Open the door.

2. Press the

mode button repeatedly until Em heat

is displayed on the screen.

3. Close the door.
