Question about Heating & Cooling
I have the same issue - and I posted this on the original thread someone else posted.
*** I had issues determining what color the "common" wire was. I have ared, white, yellow and green. Between the white and red i get .10-.70volts - between the yellow or green and red I get 28 volts.
Sodoes this mean I need better batteries - the instructions say"energizer" - but if this is the case - does it mean it is not myfurnace?
I can hear the unit buzzing atop the roof. But insideto air blows unless I turn the "fan" position to "on". - Then of courseno heat comes out.
Would be grateful for any reply!
Typically red is power green is indoor fan white is for heat and yellow is for cooling. Sounds like you don't have a common. This IS ok just means your tstat requires batteries. BUT, if your tstat turns the fan on then it's not the batteries. Is this a newly installed tstat? Sounds like you might be on "gas" setting rather than "electric" need to check the settings or sometimes on the back of the tstat there's a little switch to flip to electric. Many tstats come from the manufacture set for gas rather than electric. Good Luck!!

Thanks for the response, to be more specific, the nine pin connector was damaged, but I was able to connect the wires back to main unit panel. I am ready to hook to the hunter thermostat and do not know which wires to connect to. This is my problem and I do not want to short something out. Hope this helps, I want to get it installed again. Thanks again for caring....Jerry

Thermostat wire color codes
Please note. Not all installers use the proper color codes when they install or replace equipment. It may be necessary go go to the furnace or outdoor unit to verify what wires are for what purpose. Also be sure there are no splices in the wire that could change the wire colors between components.

SOURCE: Thermostat Wiring Problems!!!
. your blue is probably common and if you hooked it to Y you shorted the transformer or blew the low voltage fuse. Green is fan, yellow is AC, Red is 24volt. Is it a heatpump or just ac? I think its probably a heat pump and your brown is your Reversing valve it needs to be hooked to O on the new stat. If its a heatpump your tstat must be a 2heat 1 cool stat w/ aux heat. Without knowing what terminals the wire were hooked to on the old stat you may have to look at whats hooked up at airhandler( furnace) and on A/C (heatpump) tobe able to determine what goes where on the new one.

Testimonial: "Thank you, it was a heat pump"
If the Air comeing out is the same as the temp inside the RV make sure the compressor is running and not just the fans. It could be low on freon. If freon is ok then you would need to ck the wiring to the selector switch for a short. It would be obviouse because there will be melted wires. I am leaning toword low on freon since you have already been inside the wiring/control unit.
