I'm trying to change my actual thermostat (1F85U-22PR) to a RTH9585wf
I'm not sure about the wiring.
If anybody could point me in the right direction, I would appreciate a lot and also save a lot of money :)
My wiring is actually like this picture...
(I have heat and air conditionning)
RC is a red wire
RH has nothing
O/B is an orange wire
Y is a yellow wire
G is a green wire
W/E is a white wire
C is a black wire
Thanks in advance,

Thanks for the answer :)
I've called to the company (honeywell) and they also say it's not compatible with my system. They told me I should go with the prestige series instead.
I've check with the nest and they told me it should work with my system. So I think I will go with the nest probably.
Next time I will check before I buy!

This is how it usually goes:
- RC is your 24V power for cooling but probably powers both heat and cooling which would explain why 24RH (power of heating) is empty.
- O/B is usually used for reversing valves on heat pumps but could be used for 3 stage heating environments. <--This is important because the RTH9585wf is not rated for heat pumps or base board heating. You may have a compatibility issue.
- Y is stage 1 cooling
- G is for the fan
- W/E - white is usually stage 1 heating but the E could be for emergency heating.
- C is a common wire usually needed for smart thermostats, or running the thermostat without batteries.
