Hello,

I studies everything from manual and website.. but I couldn't find specific information I need before I replace the thermostat.
Ok, what I have is Goodman A42-15 with Janitrol 7 wires thermostat, which labeled below:

Y, G, R, O, W2, E, C

And for Hunter 44550 labeled:

W, RH, RC, G, Y/Y1, O/B

So to match the wires between the two (J represent Janitrol, H represent Hunter)

J H
Y -> Y/Y1
G -> G
R - > RH
O -> O/B
W2 -> W?
E ->?
C ->?

So the only thing is missing are the "E" and "C" on Hunter Thermostat. Is E represent "Emergency" System? Or is it multi stage heat pump? Since I know this Hunter 44500 only design for single stage heatpump, but I'm not sure the heat pump that I have here is single or multi stage type? Also for "C", is it "Common" wire or not? Or you think I brought wrong type of digital thermostat?

Any help greatly appreaciated!

What wires were hooked to where on the old thermostat?

Oh.. sorry about that, the colored wires on old thermostat are:

Label -> Color wire

Y -> Yellow
G -> Green
R -> Red
O -> Orange
W2 -> White
E -> Black
C -> Blue

Thanks for respond,
Scott

Are you sure the hunter is a heat pump stat, and not just a 2 stage air conditioning?

I looked it up, that's not a heat pump stat, you will need to purchase a heat pump stat.

That is what I thought, So, the Goodman Model A42-15 Heat pump is single stage or multi stage? Or ? And what is the differences when you use the words "Heat pump stat"

I want to learn!
Thanks again!

Also, what thermostat do you recommend? I can't remember the brand name from old house I brought long time ago that have humidity level indicator, so I have been looking for this type of thermostat that show humidity level.. but had a hard time finding it.

It looks like it's just single stage, There are many thermostats on the market, you are looking for a single stage heat pump thermostat, it should be clearly labeled on the box. Honeywell and white-rogers both make pretty good thermostats. It just depends on how much you are willing to spend.

Thanks for all the help. I found Ritetemp model 8085c cover pretty much for everything I need. Including the humidity indicater (and control), along with 7 days program touch screen. Pretty nifty!

Thanks again,

One stage for electric heat and the other stage for heat pump. You will need a 2 stage heat

That would be a heat pump thermostat.
