Thermostat Wiring Blue 4M
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?
