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 the arrow
under the button moves to
Em heat
on the
screen.
3. Close the door.
