Using Emergency Heat (Heat Pump Systems Only) - Carrier Edge TP-PRH Owner's Manual

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.
