I need some help.

Freon went out last week on the HVAC unit upstairs. Got it fixed, found out the next morning the thermostat was on the fritz (it was like 64 degrees up there, A/C still running, thinking it was 88). So we replaced the thermostat.

All seemed good, but it hadn't yet needed to run as it's been nice outside lately.

Cue today. I walk upstairs and it's hot as balls, thermostat says 111. I immediately turn the whole thing off, and inside of 20 minutes, it's dropped 4 degrees.

I think when it told the A/C to kick on and cool, it actually told the heater to heat. And since it never got below the 76 degrees it was programmed for, it kept running.

The wiring looks correct. I've looked at the instructions, looks correct. I validated the wiring from the pic of the previous thermostat, looks correct. I looked at the downstairs thermostat (same model), looks correct.

PLEASE HELP ME.

Downstairs, working correctly.

Upstairs, hotter than hell.

Well white is your heat and yellow is your cool and that's correct. I wonder if it's something with the DIP switch. I bet your heat pump may be in heating mode instead of cooling mode.

Brand of system and thermostat?

You really can't go by color, honestly. It depends on how it was wired at the circuit board on the unit.

I think I got it figured out. When my wife installed, she didn't do anything but wire it. There were quite a few system configurations that weren't correct, including the type of system (we have a heat pump).

It's blowing cold air now.

Yeah, you can, the colors are universal.

:facepalm:

Turn in your man car .........NOW!

Hvac anyone?
 

It's a Volvo, I'm not sure it qualifies as a MAN car.

I was not available, and she actually likes doing stuff like that. I am able, but less motivated.

And if I had to turn in a man card every time we had gender roles reversed, I'd be in man card debt. I have health issues that prevent me from doing a lot of the traditional manly roles.

I guess you get a pass for that then. :evil:

Negative ghost rider. Installers will wire things how they choose. Yes there are certain colors that should and are normally standard, but some use either brown, black or blue for the common. If you have a Ruud or Rheem their reversing valve is energized the opposite of everyone else. If you have a multiple stage equipment with multiple Y terminals or if you have 3 sources of heat. It is always best to see how the outdoor and indoor units were wired to insure you get it all back together correctly.

White=heat
Yellow=cool
Red=24v power
Green=blower
Orange=Reversing valve

I know what the **** I'm talking about here, I work on this shit all the time.

You obviously dont. Color means nothing.

Ok, the common may vary. JD1020 can now start answering all HVAC questions since he ****ing obviously knows it all.

If you can't understand the common sense about how a 5 wire can be wired up differently depending on the technician that installed the equipment then I don't know what to say.

Would you like to know how I know this? Because I was taught which colors were for what and then when I was on my first job site, my boss asked me why I used those colors. I told him because thats how I was taught. He then told me that he usually does blah blah blah. Guess what? It still worked exactly how it was suppose to. You know why? Because colors dont mean shit.
