I have an old 1980 era mercury analog thermostat, and want to replace it with a programmable one. The system coontosl a gas furnace with external compressor. The old t-stat is a general electric, and has the following wire conventions:
Wire Terminal
Green G
White W1
Yellow Y1
Orange Y2
Red RH and jumped to RC
The new thermostat, which states is for multi-stage units, is a Hunter Autotemp Heat pump multistage programmable.
Terminals avail, and wires that seem to go to them:
Wire Terminal
Green G
Red R
Yellow Y1
White W2
C
L
O
B
E
There is a designation on the terminal block for W1 and Y2, but no way to connect them (no screw terminal). I am not sure what to do with the orange wire that was connected to the Y2 terminal on the old t-stat. Any suggestions will be greatly appreciated-
