Hi,

I have a Coleman BRCS0301BB AC and a gas based heting unit. I see 6 wires coming up to the thermosat -

Red
Blue
White
Yellow
Green
Brown

I'm trying to install a new digital thermostat with 5 connectors -

Rh : Heating power supply
Rc : Cooling power supply
W : Heating signal
Y : Cooling Signal
G : Fan

Can anyone advise me on how to connect these and what to do with the spare wire?

Thanks,
Rochak
