We changed our internet provider so had to change the two nest 3 thermometers settings. This resulted in them not connecting and having to do factory resets on them both and the heatlink. Since then the hot water wont work on schedule or boost and the only way I can get it to work is by putting the heating and water on manual which is not ideal. The hot water schedule is enabled on the thermometer and it was all working perfectly before the reset so cant be a wiring issue. Any suggestions PLEASE seriously considering getting rid of them
No paperclip image when I open this in Chrome on a laptop as there would be in an email only an image of the insert/edit camera I am unable to use and some text editing tools etc.
But please rest assured the text you would see in the picture in the downstairs thermostat is "System Boiler. Heat with on/off" and The upstairs one reads "System Boiler. Heat with on/0ff. Hot water with on/off"
I can email the images somewhere if that help I can attached to email using the paperclip icon 🙂
Hey @Bilk. Thanks for the details. It sounds like you might have a stuck valve. If you hear the click sound coming from the Heat Link, it means that it's sending the signal to your boiler. I recommend reaching out to an installer.
