Dry cooler LU-VE AQE-ANQE

Good day to everyone.
I am asking for help in solving the problem.
I have a control cabinet for the aluva AQE-AQUA 5/32a dry cooling tower with a small Carel PCO3 controller, firmware SZAPPIU01-rev.10 v03.
The firmware flew off the controller. If anyone has, please share.
I will also consider suggestions for replacing the controller with another firmware.
Logic of operation of the control cabinet: step-by-step regulation (five steps) + stepless with a frequency converter.
I am grateful to everyone in advance.
