Isotherm ASU dipswitch setting BD50

[BlueSpirit.nor]

Hi - my first post to this forum.
I have an Isotherm 3701 Unit installed. Despite seperating a section in cooling Box to be used as freezer, the holding plate did not generate freezing temperature. Temperature remained at -1,6˚ celsius.
I’ve now pulled the RED ASU unit and looked at the dipswitch settings. I did find an explenation of dipswitch settings in another tread here, but assume this was for the BLUE ASU version as i didn’t recognize the explenation.

I have now changed the dipswitch in position 3, resulting in compressor working, now at -7,7˚ and still lowering temp. Control unit in manual position at the lowest setting.
Q: Did i find the dipswitch changing the Unit from a fridge to a freezer?
Q2: Is there a risk of the holding plate liquid to expand and burst the holding plate. Currently monitoring the situation with hope that the liquid will not be completely frozen in the lowest setting.
Q3: Anyone in hold of an explenation or manual describing the dipswitch settings for this RED Isotherm ASU?

Hi all, it seems like I've could my solution. Happy to share:
The RED ESC/ASU unit (Isotherm SEG00008DA) may be adjusted with dip-switch setting as follows:
Standard config (work as fridge) = only #3 in on position.
Raise temp 2c/3F (warmer) = only #2 on position
Lower temp 3C/5F (colder) = only #4 in on position.
Work as freezer by lowering temp 10c/19F = only #5 in on position.

All the best/Stein
