Hey I am trying to install my new Honeywell RTH230B thermostat. The problem is my old wiring had 6 wires connected W R O G Y C. The new Honeywell had 5 W R G RC RH I need help to connect. Anyone had this problem before?

It sounds like you have a heat pump and your new t-stat is not a heat pump stat. Is this possible?

W R G RC RH,, is not ,I don`t think a heatpump tstat
