I need help with wiring my new Honeywell RTH 6400 Thermostat.
The old honeywell had the following colors and connections:
E: brown wire
AUX: white wire
Y: yellow
G: Green
O: Orange
R: Red
C: Blue
L: Brown
Extra unused black wire.
The new system calls for:
G
W
Y
R
Rc
We used Green, Orange, yellow, and Red since there was a jumper between the Red and Rc but it's only blowing out hot air. PLEASE HELP!! IT's HOT IN SC!!!
