Hi, are you sure you are getting to the back of the thermostat, they won't be soldered in there, you are looking at the factory solders of the internal thermostat, you need to get right where the wires come through the wall, let me know.
ah, apparently there are 2 parts to this thing. I unscrewed the second face and got to the labeled wires. This is what i got:
R-Red ; T-Brown ; O-Orange ; G-Green; Y-Yellow; X2-Black; B-Blue ; W-White. Based on other research i've found most of how these would translate but not 100% sure.
oh yea, and W is i would guess jumpered to U.. they seem to be connected anyway.
Hi , sorry for the delay, U doesn't need to be connected nor does the T. , W would be AUX and X2 is emergency or E, let me know.
