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!

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.

doesn't function well below freezing (32*F) so you normally switch to aux heat (electric coils) when it gets that cold.
This is Turtle.
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.
TURTLE
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.

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 )
