There are 4 wires coming out of the wall:
red, green, blue, white.

I put in a new thermostat and connected it like this:
Rh-red
Green-green
Rc-blue
White-white
Yellow-none

The heater on auto works but "fan on" doesn't. I haven't tested the a/c yet.
I replaced the thermostat because on the old one, the auto would never start up the fan but on "fan on" it would run perfectly. Did I connect the wires wrong or soemthing?

The wiring on the old thermostat was
Rc-red
Rh-none
Green-green
White-white
Yellow-blue

The a/c auto and fan on would work and the fan on with the heater would work but not the heater auto. I'm lost, please help -- thanks
