Hey Nesttroubles,

Thanks for reaching out and we're sorry for the delay.

This link would be helpful. This shows how a Nest Power Connector is installed if you don't have a C (common wire) terminal available at your system.

I hope it helps,

Ryan

Thank you for the reply, I have seen this, link several times before, it does not resemble my common wiring at all.  That is why I attached the wiring diagram for assistance.

I go thru about a battery a week x5 thermostats

The more the furnace runs, the faster they drain, the t-Stat wires but out a solid 24V AC, then the zone is not running.

Any help would be appreciated before I put my old therastats back in place.

Hi Nesttroubles,

Thanks for the update.

Could you share a photo of your current wiring setup on your Nest Thermostat?

I hope to hear from you soon.

Regards,

Ryan
