Is this the correct wiring setup for nest.

  • That setup looks pretty reasonable to me, but you should double check with Nest. Enter your information into their compatibility checker to get a proper wiring diagram. nest.com/support/article/… – mrog Jul 6 '18 at 21:36
  • Can you post photos of the wiring at the furnace or air handler? – ThreePhaseEel Jul 6 '18 at 22:10
  • I will try and post those tomorrow. The ac is currently working so I left for it to cool down. I just wanted to make sure that the jumper from W2 to E on the original diagram was ok for the nest setup. – user1307149 Jul 6 '18 at 22:12
  • I am thinking you really need to put the white wire on W1 and not W2. Your old thermostat had Emergency heat - the Nest will automatically supply this through W1 if I am not mistaken. W2 is Secondary heat or auxiliary - your original already has a Jumper W2 to W1. Your Red Rh wire - depending on system - probably should be connected to Rc - but I could be mistaken here. Your manual should state whether Rc becomes live with 24Vac or Rh. Typically in a T-stat like this if you do not have another Rh red wire, Rc is almost always used . – Ken Jul 6 '18 at 22:24
