Pegasus PowerBox Advance - issue with setting 'Adj' parameter.

I've recently gotten a PPBA and tested this out.
When I change the Adj voltage to off I can't set it back on again, it goes back off directly.
Any idea what's going on there?
I intend to use this output for fan speed control. Need fan speed to be high in the start, before imaging.
Then as I do the alignments I switch it to low setting and it's off during the rest of the night.
The dew heater outputs would potentially be good for this, but I both use them (main & guide scope).

I'm using a Mele quieter with Kubuntu, Kstars & indy from PPA mutlaq.

Thanks a lot for your suggestions!

Dear all,

I've gathered logs, that can be read in the 'spoiler' below.
In the last lines I think there are some parameters / settings written to the PPBA.

In my setup, I use the adj output for speed control of the cooling fan.

Behaviour:
- Adj output starts of at default 9 V -> Fan is turning.
- Set the 'adj' voltage off -> Fan goes off.
- Set the 'adj' voltage to 9 V -> Fan remains off. (selector also toggles back to 'off', although sometimes it keeps displaying '9 V'.

Second test:
- Adj output starts of at default 9 V -> Fan is turning.
- Set the 'adj' voltage to 3 V -> Fan turns slow.
- Set the 'adj' voltage to 9 V -> Fan turns fast again.

- Set the 'adj' voltage off -> Fan goes off.
- Set the 'adj' voltage to 9 V -> Fan remains off. (selector also toggles back to 'off', although sometimes it keeps displaying '9 V'.

Expected:
- After switching off, it can be switched on again at a certain 'adj' voltage.

Thanks so much for your help!
