Raymarine ACU400 debug level?

[Goudurix]

Hi,
I recently installed a Raymarine ACU400 autopilot controller with P70s control screen, steering a Lecomble & Schmitt hydraulic piston on my 37ft sailboat.
After an issue with the bypass valve on the drive, that was repaired, I redid the setup of the ACU400 system and the recommissioning.

There are 2 parameters that can be set but on which I cannot find ANY information in the supplied manuals:

- Debug level
- ACU debug level

No info in the manual, they are only mentioned as "existing".
Impossible to log into the Raymarine Forum - the site seems being rebuilt.

Anyone knows what they are used for and how to set them?

Thanks in advance,

Jan
