Need both Aux and Emergency Wires?

[CR8]

I have heat pump system (not a duel fuel system) that I'm wondering if I can connect a Nest Gen 3 Learning thermostat to. I have G, R, O, Y, W2, X (Blk), and E (Brn) wires. How should I wire this? Can I put W2 in W1, X in W2/Aux, and E in *(star)?

Hey CR8,

Sorry for the delayed message. I wanted to follow up and see if you are good to go? Please let me know if you still have any questions about the compatibility of your system.

Best regards,

Jake

I do still have the same problem. I tried to hook it up many different ways but still no luck. I have the same question. Wondering if there's a way to hook it up that I haven't tried. Thanks

Hey there, 

I'm so sorry for the delay in our response, but I wanted to hop in here to make sure we addressed your concern. I can definitely understand the confusion when it comes to thermostat issues as it can be very odd to figure out sometimes, but I'm happy to look into this for you. 

First off, I would suggest using the Compatibility Checker to see if your system is compatible. Then, if it is, I would suggest contacting a pro to come out to help you with this since I know that the Nest thermostat is not compatible with stranded wires, every wire has to be connected to the Nest Thermostat system. 

Please let me know if you have any further questions or concerns as I'm happy to help. 

Best regards, 

Garrett DS
