Hi There - Hope someone can help and explain in plain language. I have a google nest connected 1 to underfloor heating, and 1 for central heating - what I have found is that even though on screen it shows say 20d, when I turn it up to 20 the heating does not start, it starts when I go up by 2-3 d of what is showing on the screen. Why I am not ablet o set a temp of say 21 d and get the system to start?
Thanks for reaching out. Let's take a closer look on why your Nest Thermostat won't turn on the heat. To isolate:
I'll look forward to your response.
I wanted to check in with you again to see if you still needed any assistance. If you continue to experience any issues after this, do let me know so that I may look into it more thoroughly.
