Nest thermostat

[Súpernazareth]

I am installing a Nest Thermostat. I have Y, O, W2, R, G and C wires. The Nest Thermostat doesn’t have a connector for the W2. Where shall I connect the W2 wire?

Do you have a heat pump system?

which nest model do you have? 

You can try to connect it to W or W1 or 

* slot. With the wires you mentioned sounds like you have a heat pump system with 2 stages of heating or back up heat. If you don’t have a W2 you won’t be able to use 2nd stage of heat or back up heat. Hope that helps. Good luck.

Hi HVAC,

Thanks a lot for responding,

Yes. I have a Carrier Heat Pump that came with an electric back up heating unit. I am trying to connect to it a Google Nest Thermostat (not the learning or the E model).

Just to be sure that I understood it, I shall try to connect the W2 wire into the W slot of the Nest Thermostat. Is that correct?

If yes, I will connect the W2 wire to the W slot and all other wires to the corresponding slots. 

Thanks again!!!

Hello everyone,

I wanted to ensure that everything was covered here.

Thanks for looking into this, HVAC.

@Súpernazareth, I appreciate you reaching out to us. In addition to what was mentioned above, connect the W2 wire to the W/W1 terminal on your Nest Thermostat. You will be prompted during the setup process about its function; make sure to choose the appropriate one for the configuration.

Feel free to let us know if you have more questions in mind.

Regards,
Mark
