Argh! :eek:My husband installed a new Hunter 44360 5/2 programmable thermostat and it worked for the A/C however it is time to run the heater and it doesnt work.:confused: I dont know how it was set up before and he can't remember. Here is our current set up. Please help!! its getting rather cold.:(

G= GREEN WIRE
RC = YELLOW WIRE
RH = BLUE WIRE (WE ALSO TRIED JUMPING RC AND RH)
Y/O = RED WIRE
W/B = WHITE WIRE
Y1 = NOTHING

Hunter,, if you got a couple months use out of it for a/c,, its probably worn out,hunter is junk

Agree with wmproop, but I will try to help.

First, need to know what type of heating system you have. Gas forced air, or heat pump? If heat pump I'm not familiar with wiring. If gas I may be able to help.
