Hot water work not on schedule or boost needs to be switched on manually, heating fine

[Bilk]

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

Hey @Bilk,

Thank you for reaching out! I'm sorry to hear about your issue, but I'll do my best to help you sort this out. Does the heating work as it should from the app?

[Bilk]

Thanks, yes heating still works find and shows orange in app either by schedule, boost or manual. Hot water however needs to be switched on manually, as even though it says on the app its working it is not

[AnaM]

I see. Can you send me a picture of what you have in Settings> Equipment on the thermostat's display?

Hello there. Just checking in. How's it going with your thermostat?

[Bilk]

I am struggling to upload images however the downstairs thermostat says

"System Boiler. Heat with on/off"

The upstairs one reads

"System Boiler. Heat with on/0ff. Hot water with on/off"

Thanks for the help

Thanks for letting me know. You should be able to find a paperclip icon in there to upload pictures. It would be easier from a computer. 

[Bilk]

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 🙂 

[DragosC]

No worries. Thank you very much. Could you tell us please if you were able to reset the schedule on the thermostat for the hot water? 

[Bilk]

Yes i have reset it. It does not work on schedule. If i press boost the heatlink clicks but the water does not heat unless i manually switch on the heating 

[CristianC]

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. 

[Bilk]

But then why would it work when i hit manual on the heatlink and why did it happen just after i reset the internet on it? If i turn on the heating via the app it works it is just boost that does not. It is not a valve

[DragosC]

Could you tell me please if you have a multimeter at hand so we can conduct a continuity test? 

[Bilk]

Can get one for tomorrow what do you need me to do?

[DragosC]

I've sent you an email with the steps. Let me know how it went please. 

[AnaM]

Hey @Bilk,

Let me know if you still need assistance.

[Vladut]

Hi there, just checking in with you. Do you still need help?

[Bilk]

Yes. Just got multimeter so will run test today

[AlexD]

Awesome. Keep us posted with the results. You can reply to the email with all of them.
