Scheduler not working 4th Gen

JonF — Thu, 08 May 2025 13:05:43 GMT

Looking for help! I have been a Nest Thermostat user since Gen 1 and have never encountered the problem I am having now, and cant figure out. The use is A/C only, connected to a two stage system. I use Y1, Y2, G, Rh and C. The scheduler is not activating a change in temperature. The thermostat acts as if the scheduler is not existent. When I manually change the temperature for my Home app on my IPhone it changes correctly. Any ideas?

I appreciate the wiring information you provided me. To get a better understanding of the situation, please help me out by answering the following questions:

When did you install the Nest Learning Thermostat 4th gen.?
When did the issue start?
Have you done troubleshooting steps? If so, can you please list them?

I replaced the Nest with a new Nest (full replacement, including wiring bracket), so I believe the issue has to do with wiring to the a/c unit, but it’s beyond my understanding. Looking for suggestions!

I installed an ecobee and the problem was resolved. Therefore I now know it was not the wiring, but was a communication problem with the Nest. Google will never admit it is their problem, and I will eat the cost as I have already spent hours with Google’s help team.

I did swap the Nest with another Nest (that was the Google resolution) and it did not fix the issue.
