I am trying to replace my old style thermostat with a new Honeywell. My old wiring setup: Green to G-F Yellow to Y-C Red to R-V White to W-H Blue to 4-M That is the labeling on my old thermostat. My new thermostat has the follow labels: W Y G R Rc There is currently a jumper for R and Rc they say to remove if you use Rc. Both heat and HVAC are electric. No heat pump as far as I know. So where does the Blue wire go? Rc?
