Hi, I have had my nest thermostat's 2nd generation installed for 10 years now & never had any issues. Suddenly 2 days ago 1 of my nest thermostat is reading No power to c wire E29 error code. My c wire is & has been connected & nothing has been touched or moved or replaced. What is goin on all of a sudden?
I have 4 zone Taco & 3 thermostats.
The e29 code is thermostat that controls HVAC the other 2 heat only.
I swapped thermostats to check if unit was bad, but still have same issue.

Hi, I have had my nest thermostat's 2nd generation installed for years now & never had any issues. Suddenly a few days ago 1 of my nest thermostat is reading No power to c wire E29 error code. My c wire is & has been connected & nothing has been touched or moved or replaced. What is goin on all of a sudden?
I have a 4 zone Taco & 3 thermostats, Zone 2 is the one that is not functioning which is the HVAC system, the other 2 thermostats are working
What can I move around or switch? Each zone has 2 wires on the Taco box so I’m a little confused
