rockyteeer · #1 Jul 6, 2006, 08:46 PM

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

yeah I have tried most of the solutions I have read about on several of these pages, yet no luck.

I have determined that the Blue, Yellow, Orange, Red, White wires go to the AC and
additionally the Green, Red, White, Blue wires go to the Furnace.

So.... how should I connect a five wire programmable thermostat?

Does anyone have a clue?

thanks.
