Hello.
I have an old Friedrich Thermostat (still uses mercury) running my heat pump furnace. I bought a new Honeywell thermostat and im confused on where to put the old black wire, along with the W1 and W2. In the instructions it says that if I have both a Y1 and W2 and W3 wires that i should ask for help.
Here are the wires my old, existing thermostat has:
F- White wire
Y-Yellow wire
W1- Green
W2- Blue
O-Orange
R-Red
#5- Black. (New thermostat does not have a #5, whats this wire for??)
NEW thermostat terminals:
B
O
G
Y
W/Aux
R
Rc (R and Rc terminals are jumped)
In the instructions it says that the "W/Aux" terminal can be used for W, W1, or W2. But I cant put BOTH of my w1 and w2 wires in that terminal can i?
Thanks everyone for looking and for the help.
