Carel PCO3 Large - Budzar Industries Password

Hello,

I have purchased a Carel PCO3 Large board which apparently instead of new it has preloaded software from Budzar Industries recently acquiried by Multistack LLC.

I cannot find any service manuals or info regarding the model WM-125-S which is displayed on PGD1 screen and I am stuck at a Screen:

Enter Factory 0

0 0 Password:
000 000 000
000

I want to reset the board to use it in a different machine and cannot find the codes.

Any help greatly appreciated
