I have a zone ac/heat system and I put in a nest and 2 nest e.   The neat e have power issues since there is no cwire so I bought a 24v adapter.   It says put one with in C and the others in RC but there is no RC on nest e.  Where should I put the second wire?

Hey Bryan,

Having power issues can be troublesome and a bit confusing. Let's jump in and see if we can get the issue resolved for you. If you are unsure on how to wire the device to the adapter, I would recommend having a Nest Pro come out and take a closer look. If the device is not properly wired, it could result in damage to your HVAC system. Please let me know if you have any other questions from here.
