VisionPro IAQ question: how to tell if Aux heat is on

[doinkeroni]

Hello, I have a 17seer 2 stage comfortmaker heat pump with 2 stage electric strip auxillary heat. I have the lockout temp set for about 10F (so that I don't damage the compressor) but this morning it was about 5F Outside, the Heat Pump was off, but the thermostat still says "heat". How do I tell what stage of heat the thermostat is using? Is there any way to tell if it is kicking in the auxillary heat at all?

Thank you!!

Watch your electric meter, you will know when the electric heat strips kick in.

I have a dual fuel setup, and mine says "aux heat on" when the furnace kicks in.

If the outdoor unit isn't running. And its still putting out warm/hot air. the aux must be on.

PS: Running the heat pump at 0° outdoor temp won't hurt it.
And will probably save you money on your heating bill.

From page 4 of the Operating Manual, the display should read Aux Heat On.

the visionpro 8000 has a red led in the corner that comes on, im not sure if the iaq has it though

If you have electric resistance as auxiliary heat, I wouldn't lock out the compressor.

You won't hurt the compressor by running it at low temps. The aux electric heat will cycle on/off as needed while the compressor runs continously.

My 14 SEER 9 HSPF heat pump has a C.O.P of 2.47 at 10F ambient. That means it's 247% cheaper to run than electric resistance heat.

Take care.
