replacing old thermostat and I have to many wires.
Hi there
We were lucky enough to get a Lowes gift card for Christmas so today we went and bought a programmable thermostat.
My wife read somewhere about how they can save us money on our heating / air con bills.
Our old one is from when the house was first built I think (so at least 20 years old)..
new one is a Hunter 44550
old thermostat seems to be no name brand..
Old Wiring
letter designated on old thermostat followed by wire color..
c = blue
G = green
Y= yellow
R = red
W2 = brown (or it may be black)
W1 = white
O = orange
The new thermostat has spaces with the letters..
W
RH
RC - there is a jumper wire between RH and RC which it says are for 2,3,4 wire systems..
G
Y/Y1
O/B
We have read that as the new one is battery powered we should cover up the C=Blue wire as that isn't needed anymore..
The thing that is throwing us is that we have a W1 and a W2 wire but only one space on the new thermostat for W..
We have tried their help line but it is closed till Tuesday..
Any help appreciated, I don't really want to damage something major by messing about.

C terminal
It is always a good idea to use the C terminal; it keeps the stat working when the battery goes dead. Otherwise, the stat stops working. I'm surprised the instructions advised otherwise.
