looks like an old white rodgers tstat. do you have a picture of how it was hooked up before changing? wiring ect?

Customer: replied 10 months ago.
No. Sorry.
Expert:  Kcrand36 replied 10 months ago.

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?

Customer: replied 10 months ago.
The old thermostat wures were not labeled. I assume "R" for red, "G" for green etc.
Expert:  Kcrand36 replied 10 months ago.

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 ..........
