Wiring Compatibility With Chronotherm Honeywell

[JBliss]

I have a Honeywell Chronotherm Thermostat with 4 wires coming out of the wall. 

White going to W post

Blue going to Y post

Green going to G post

Red going first to Rc post then continuing to the Rh post

Nest instructions say I do not need a jumper but I am not sure which Post I should put the red wire to    Rc or Rh

Any help would be appreciated.  Jon

Hi JBliss,

Thanks for reaching out and we're sorry for the delay.

There's no need for the jumper wire to be connected to your Nest Thermostat as these 2 (Rc and Rh) wires are already connected electronically. You could use the Rc terminal as it is how it was connected to the previous thermostat. 

Let me know how it goes by replying to this thread.

Best regards,

Ryan
