Question About Honeywell Thermostat rth230b
Heat Won't Turn On...

I have replaced an old thermostat with a RTH230B. I have 5 wires, Red, Blue, White, Yellow, and Green. I had the A/C working, but now I cannot get the heat to work. I have the Blue going to Rh and the Red going to Rc which works for AC but not heat. The W is White, Y is Yellow and G is Green. Please help, I'm freezing!
