The home I just bought has a natural gas heating, with central AC, and a humidifier. The curent thermostat is a honeywell RTH5100, i just bought a honeywell TH811OU.
The wiring on the current model is:
RC jumped to R
RED - R
ORANGE - Y
BLACK - C
BLUE - W
GREEN - G
BROWN - W2
I tried wiring everything the same into the new one:
Red - R
Orange - Y
Black - C
Blue - W
Green - G
I don't have a W2 aux on the new one... and the only remaining jumpers are S1 and S2 which are for optional outdoor remote sensors.
THe problem is that when i put the new one on, the air conditioner does not work. I didn't try the heat though. The furnace fan works.
I had to put the old one back in to get the airconditioner to work again.
Anyone know how i can install the new thermostat? thanks
