I have a Carrier heat pump, comfort series that was installed five months ago. I want to confirm the settings in the thermostat are correct.

The stat is EDGE programmable thermostat

I don't want the owner's manual codes, but the one the dealer uses by holding on the fan button and getting codes on the bottom right coner.

I tried calling the dealer, but they are to busy to verify the stat. I already had one issue that the dealer walked me through over the phone. I changed code 8

I just want to verify all codes are correct because I had one issue already.

What would I set Option 08 — Auxiliary Heat Lockout Temperature Setting at. -3,-6,-9,-12

I just want to make sure that everything is set correctly.

Manual says:

Code:

Option 08 —Auxiliary Heat Lockout Temperature
This selection is available on heat pump systems with a valid outdoor
temperature sensor connected. Available settings are: Off, 5, 10, 15, 20, 25, 30,
35, 40, 45, 50, 55.
OF (off) -- function is disabled. Auxiliary heat is allowed to operate whenever
sufficient demand for heat is available.
5--55_F -- Outdoor temperature above which the auxiliary heat is not allowed to
operate (unless MODE is set to Emergency Heat).
Default is OF (off).

Essentially what this will do is not bring on EM/Aux heat no matter how much you increase the temp on tstat, if outdoor temp is above this value.

I would set it to the lowest possible value you HP can satisfy the tstat and you are comfortable at. And also depending if anyone in your household love to mash the increase temp button the minute they get a chill. ;)

So maybe 30, 35 or 40
