I have a new Honeywell thermostat to install when I take the wires off the old unit there are 5 wires. The coors are Red, White, Yellow, Blue and Green. I can hook up the first 3 to the new Thermostat but on theinstructions it has a Rh (R heating)spot and a Rc ( R cooling) I don't knowif the blue wire should go to Rh or Rc, likewise for the Green wire. Can anyone help? The telephone help lines don't open till Monday. Thanks!

Red wire to Rh
G is green
And yellow is Y
Blue is Rc
White to W or C for common
