We had an older CArrier thermostat. The old wiring went as follows...
Orange = o/w2
Red = R
y/y2 Yellow
G = Green
C = Black (Common)
W/W1 = White
New thermostat has the following
W
Y
RH
RC
G
We have hooked this up every which way and the only thing that will come on is the heat. Can anyone help? Thanks!
