Hello

I would like help about my Nest Learning thermostat wiring.

1) is it compatible ?

2) what should be the wiring setup ?

From a previous post last September, Patrick_Caezza answered :

White - W1 to W2 (set as AUX heat)

Red - R to Rc (jumper to RC not needed)

Orange - O to OB

Yellow - Y to Y1

Green - G to G

Blue - B to C

I read that my wires S1 and S2 are for inside and outside temperature. What should I do with those 2 wires in the new Nest Thermostat ?

Also, for the R red wire I’m not sure what means “jumper to RC not needed” . Should I connect or not to arc ?

Hello Jake, thanks for the reply

My Nest thermostat seems working well. I did not connect my 2 old wires used for outside temperature. Other wires were connected as wrote above
