| Jun 4, 2020 at 20:12 | comment | added | David Li | Thank you for the response! I do understand the 'power stealing' problem. I have a common wire, which is why I thought nest would be OK and bought one. My home is a new construction and I can trace the common wire to the transformer in my air handler. I also measured the voltage between the Y and C at the thermostat, which is around 27V. The nest support said it might be the C wire providing too much power and it's feeding back to the system. Another suggestion I got is add some resistor. | |
