After an answer on this site I purchased a new thermostat today capable of central heat/cool and also for a heat pump. It is the Honeywell RTH6400. I currently have a White Rodgers (9510E7) rectangular thermostat. I am still having problems figuring which wires go where.
Currently there are 8 wires coming out of the wall
Blue- not connected to anything
Black- not connected to anything
Red- R
Brown- C
Yellow- Y
White- W2
Green-G
Pink- O
The new thermostat only has room for 5 wires (6 counting the "NOT USED" outlet). The outlets are:
G
W O/B
NOT USED
Y
R
Rc
*Jumper wire between Rh and Rc.
Some are obvious:
G-G
Y-Y
R-R
Rc-None
The instruction manual says not to connect C, just wrap with electric tape.
But I am left with O and W2. The instructions say to connect O to the W O/B outlet. If this is the case, then where do I connect the W2 wire? And if I were to connect eh W2 wire to the W O/B, then where do I connect the O wire.
Please help! Thanks in advance.
