TROUBLESHOOTING
What if ther e is a green light on in the upper corner of
the display area?
This thermostat uses a green LED to indicate auxiliary heat and
emergency heat operation on the Heat Pump model. This green
light means one of two things.
1. Auxiliary Heat is on:
This light turns on automatically when the system
determines that it’s too cold outside for your heat pump to
heat the house without help. So, it’s getting help from the
electric heaters.
NOTE: This indicator does not reflect a problem with your
system.
2. Emergency Heat is on:
If the heat pump is not working properly, you can manually
select the emergency heat for extra he lp in heating. You’ll
know there’s a problem if the house can’t seem to get warm
when it’s 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 .
