Have HVAC Questions? Ask an HVAC Expert for Answers
Hello, I am Kevin, one of the Tech's here on JA.
I see your asking which wires go where?
are you changing a thermostat?
and what are you changing to?
what thermostat did you have prior?
looks like an old white rodgers tstat. do you have a picture of how it was hooked up before changing? wiring ect?
so you have taken the old thermostat off, and replaced it. ? did you replace wire for terminal designation? in other words, if it was "r" you hooked to R, and "w1" you connected to W1 or W?
they may not have been labeled, but on the thermostat, they must have been. This is important. Otherwise, you need to start from scratch, trace wires to there designation and so on ..........
