Apologies if asked before...I tried searching, but after several pages gave up and am posting new.
When a thermostat calls for aux heat, the aux heat does go on....but
how does the system determine whether 10kw or 14.4 kw will go on? Is
it timer-based?
My GeoMax 2 (Heat Controller Inc) (2 stage compressor) has a 2 stage electric backup/aux heat....first stage is 10 kw with a 50 amp breaker, and 2nd is another 4.4 (Total 14.4 kw) on a 20 amp breaker.
Aux heat has come on a couple times lately because here in PA, it's gotten really cold, really fast.
I have 2 honeywell Visionpro 8000 thermostats and a honeywell zoning control panel.
The zone control panel is wired correctly (as far as I can tell) to the heat pump, with Y1 and Y2 (1st stage, 2nd stage compressor) and also a W/E (aux heat). But that's only 1 control wire for the resistance heating.
How can I tell if all 14.4 are going on at the same time, or the system is staggering them? Ideally, the thermostat would be "4" stages of heating, with the first 2 being compressor, and the last 2 being aux (10kw) and aux (14.4kw), but I know I don't have that setup.
