The new tstat won't work with your system. You need one that can handle a separate RC for cooling wire and RH for heating wire. Check HDepot or Rona for some of the better Honeywell electronic tstats and look at the box info/wiring diagram or open it and check the wiring diagram B4 bringing it home.
