E/73 no power to the RC wire.
I get this error message on a regular basis. Usually when it’s supposed to be heating. But if you give it a little bit then it miraculously turns back on. We change out the filter monthly, regardless of dirt level. That seems to help. My Wi-Fi is connected, the battery is fine. I have had professionals come look at it, they can find no issues.
it cycles off and on.
according to the diagram it looks like it is a learning nest, GEN two.
I love being able to change the thermostat from a different room or when I’m not at home but I am super aggravated when I wake up in the morning and it’s freezing in my house! it does it in the summer also, but I’m usually in the pool so I don’t complain as much. Lol.
if my smart home cannot figure out how to be smart enough to work when everything is attached properly… And apparently it is not that smart!
if anyone knows something that I have not tried, please let me know. No I don’t want to call in the professionals again for them to look at it and tell me that everything is connected properly again.
i’m not buying a new furnace/AC anytime in the near future when mind works just fine.
