Nest Heat Link Beeping

[OldChestNuts]

Today, the Nest devises smoke /carbon alarm and the Heat Link beeps every minutes.
The smoke/carbon alarm stopped beeping now after I disconnected the batteries and reinstall the batteries.
Now the Heat Link still beeps once every minute. Not sure what this means. Anyone got any clues?

I had this problem a few years ago, change the batteries!

Change the batteries in the Heat Link? Not sure if this have betteries?
The batteries in the smoke/carbon alarm is still good, measured 1.6v.

What do you mean by the heat link?

[OldChestNuts]

On the Nest system, you have a wall thermostat device with display that talks to the heat link device. The heat link device is the box that connects to the boiler.

The voltage on the lithium battery measured 1.6v offload. But if the battery is exhausted, it would normally measure below 1.5V as I used these before in other devices.

I will have to install the Nest app and see what happens. Just moved in to the property with these gadgets and no instruction was left for new occupier.

You’ll need a Google account (email) to link to the Nest.

And no, the heat link doesn’t have batteries nor does the main control unit.
