T-Stat wiring question
I have an old Lennox heat pump(15+ years old) and a Honeywell CT70A t-stat. I think it was wired incorrectly. Here's what it has:
Orange - X
Pinkish/White - E
Red - W1(jumped with Y1)
Black - O
Green - G
Brown & Blue (2 wires) - R
Yellow - W2
Also there is a second set of wires (red&white) in their own conduit not connected at all.
Is this correct?
why do you think its wired wrong?
what you'll need to do is find someone who is familiar with control systems come over and check. the problem is that just because a wire is a particular color doesn't mean it is connected to the right wire at the unit. The unit will have to be checked to see what wire goes to what.
Heat pumps are color blind.
This is not a DIY site, please read the rules, thank you.
Wow....it took you 15 years to figure out you had a problem.
Maybe another 15 and it will be fixed.
Call a professional. This is not a DIY site. Read the Rules.
