Nest thermostat 3rd Generation lost power

[KenB]

On checking heat link with multi meter, 230v power into unit ok but no 12v supply from unit to thermostat. No green light illuminated on unit. Reset tried but to no avail consistent with unit failure.

How can we get a replacement heat link?

The unit is still within 2 year warranty.

Hello @KenB,

Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.

Here are some helpful troubleshooting steps:

Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs

Could you also help me with some answers to these questions?

How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
If yes, was the power properly restored at the fuse board after work was done?
How many zones are present in the setup?


Regards,
Cristian
