Eurotronic Spirit Zwave-plus inclusion

[Westcott]

Hi,
I've just got one of these, and it doesn't go into inclusion mode.
Eurotronic have so far not replied to my support email.

When the batteries are inserted, the display shows "1" then "3" then "4" and then "5", and a brief whirring sound.
Nothing more happens, no button presses have any effect.
Just the same when I try a factory reset.

Does anyone have an idea what is wrong?
Thanks

Looks like you haven't installed the thermosat on your radiator yet and it fails on setting the open & close position.

Hi Knielen,
Thanks, yes I thought that too.
However, it does the same thing when mounted on a valve.
No error codes are shown, it just stops on "5"
The instructions seem to say include it first, then mount it.

It was a defective brand-new valve!
The replacement from Amazon works correctly.
