Switching heating on

[Jongreen-147]

Hi, I've had my nest installed for a little over a year and it's been great, until a few days ago when the heating stopped responding to the thermostat or the app.  Hot water switches on fine from the stat and the app still.   The only way I can get the heating to come on is to press the button on the front of the heat link.

Any ideas?  Faulty heat link?

Thanks in advance, Jon

We just woke up to a cold house and appear to be having the same issue. Thermostat showed set for 69deg and house was down to 61deg but the heater was not running until we pushed the home screen button

I'm having similar issues. Where do I find the home screen button?

thanks!
