Need help wiring Honeywell Thermostat from White Rodgers

mrx900 · 10-17-2009, 07:56 PM

I am installing a new Honeywell theremostat and the wiring is confusing. ON my white Rodgers (old), there are two yellow wires, going to the Y screw..and the red has two wires going from RH to Rc....but nowhere on the Honeywell is anything like that...just one R and one Y. Anyone know what goes where? The manual also states a "jumper"..and im not sure if its that metal thing connecting Rc to R or somethign else.....I managed to attach the white and green wires, since that was easy (1 wire each)....but the yellow and red has me confused...

thanks.

On the new stat put the Yellow to Y, Red to R or Rc and leave the jumper in, White to W and Green to G

Make sure you read the manual and make the setting to convential not heat pump

so is the Red wire going from Rc to RH on the White Rodgers considered a jumper? Do I just need to connect the red (R) wire to the R spot on the Honeywell ?

Yes the red wire is a jumper and as I said before put the red wire to either R or Rc and leave the jumper that is there between R an Rc

I too am having trouble installing a new Honeywell theremostat. ON my white Rodgers (old), there is 1 red, 1 white, 1 blue and one green wire...
Does anyone know what goes where?

at the subbase....Red-R (if you have Rh on base jump it over) WHITE to W Blue to Y Green to G.go down to the furnace an see if you pick up the colors connects to verify that Blue is the Y.. Y=COOL W=HEAT G=FAN R=HOT from TR.the reason for the jumper from R/Rc to Rh on any subbase..is the transformer is in the furnace and in the heating mode you need to pick up the HOT/R to get the HEAT to runlets hear back if problems......shut the 115V toggle off on the furnace when working on the wires thru the subbase.
