Hi there,

I have moved into a house with a heat pump and electric backup
'toaster'. When the fan is running, sometimes the auxiliary heat light
is on, and sometimes its not. Is this the backup electric resistance
heater coming on or what?

Also there is a switch for Emergency Heat, that you can turn on
manually and has a red light. What is this doing?

Thanks very much!

Dean

It usually does mean the backup heat is on but there could also be outdoor
air temp lockout thermostats on it so it may not actually be coming on.

turning this on means you will heat with the backup heat only ( the heat pump
is turned off when you switch this on )

... He who laughs last probably made a backup.

i can't see it from here but it sound like when the thermostat gets 3ºF or more
behind the back up heat / red lite comes on to keep the heat needs up on the
house.

The Emergency heat Switch : This is to just turn the heat pump off and switch
over to just back up straight electric heat. This Switch is for times when the
heat pump goes out and not working and you want heat and want to over ride the
heat pump system and just use straight electric heat back up. By what you have
said, you will never need the Switch for your system will switch over to back up
heat automaticly and keep up with the heat needs.

Auxilliary heat and Back up Heat is the same Meaning or word. Now here is what
you may want to hear. Auxilliary heat means when you just want the heat to be
added to the house. Emergency Heat means when your in trouble and freezing to
death. You use the Emergency heat. Now Both are the same thing.

Remember, a heat pump is simply the a/c compressor running in reverse. It
doesn't function well below freezing (32*F) so you normally switch to aux
heat (electric coils) when it gets that cold.

I usely set the outdoor thermostat to switch the heat pump off and the electric
strips on at about 25ºF outdoor ambiant. This way the customer does not have to
worry about it.

Yes, it supplements the heat pump when necessary. It can also indicate
a problem if it is running extensively in mild weather.

The "emergency heat" means you're heating with the "toasters" only and
the heat pump is disabled.
