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!
