Eurotronics Spirit Value Controller Z-Wave plus Disable Buttons

One of my Spirits has locked itself … I let it deplete the battery to 0% and when I changed it the child lock appeared. I am unable to turn it off by pressing + and - for 3 seconds, as stated in the manual. So I presume it is locked with this mode (0x02) that I cannot change without a channel.
I’m running openhab 2.5.4, I guess its stable. I tried removing and adding the thing and I got one new channel (Basic deprecated), but no protection channel.
I have 7 Spirit valves and I could try removing them all and uninstalling zwave bind, as I didn’t do this since the original install about 1.5 years ago. But I would like to know if this will solve the issue beforehand, or do I have to get some beta binding to get this channel.
Ideally I would like to also upgrade to working Basic channel for setting MANUAL mode (type31 for direct valve control) from this topic, that also doesn’t seem like it’s working yet: Eurotronic Spirit - Unsupported mode type 31

Please advise.

BTW, here is the link to the English manual for the Spirit:

Thanks and best regards!
