Please help. I have the following connection on my old thermostat:
Y - Yellow wire
G - Green wire
R - Red wire
O - Brown wire
C- Blue wire
W2 - White wire

I have the following options on my new thermostat:
G
W/B
Y/O
RC
RC1
RH
Y1

From reading other posts, I have come up with:
Y - Yellow = Y1
G - Green = G
R - Red = RH
O - Brown = Y/O
C - Blue = RC
W2 - White = W/B

I have not connected this unit, yet. I have read where RC and RH are jumped.
The instructions on this thermostat state to remove the RC - RH jumper
for 5-Wire Systems. Please confirm or correct my attempt to install this unit.
Thank you.

Take the blue off the RC post

As the manual says on page 11 "NOTE: If a wire marked “C” is present, DO NOT connect it to the thermosat." You thermostat is battery powered only and will not power from a transformer.

Thanks. Perhaps, I should have read the manual more carefully.

No-where, not needed with a battery only operated tstat

Thank you for all the help. I connected the thermostat and everything seems to be working great. I did have to jump the RH and RC connection. I do not understand why I had to jump it when the directions indicate not to. Thanks again.

Did you try your heat also to make sure it works?? Did the ould stat or the new have emergancy heat?

The heat is working also; I just checked it. Neither of my thermostats have the emergency heat function. Thank you.
