Have HVAC Questions? Ask an HVAC Expert for Answers
Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly I am not paid anything until you rate my service good using the STAR RATING LINK at the top of your page, the money is paid to the site not me directly.
Yes if you have a picture of the current connections that would help
I would leave the black wire capped....the white should be your regular heat and Brown is likely emergency heat... So White should go to the normal W connection or AUX for heatpump purposes and Brown if you can on the next it would go to W2
All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am paid anything through the site and that will also get you a DIRECT LINK emailed to you to get back to me!.....tips are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!
You have a heatpump correct?
Yes it is a heatpump for sure, you need to read the labels on the bottom of the original that is where you need to hook them up on the new one, disregard the top labels.
You should use White...in there and cap off brown for now...Brown is likely the EMERGENCY heat wire they should not have put in there...
Try to put White to AUX terminal and try it if it does not work you can connect Brown to it as well, even though the NEST says not to connect two wires to one terminal you still can do it just like the old one. It will not hurt anything.
Yes so put WHITE in AUX and BROWN in E
Yes it would be pretty obvious, but WHITE is always AUX and Brown is always Emergency heat so I doubt it is wired backwards.
I was just touching base with you because I have not heard back from you and the question is still open and unrated, if there is something else I can help you with follow up questions are free and can still be handled even after you rate the service thanks.
