Sobsno on appearance can be determined.
If he somewhere has a port for communication with the outside world, such as modbus or 232, then you can.
You can disassemble and look for the uart on the board there, in the hope that the manufacturer left a loophole and there is some debugging data there, but you need to find someone who understands the essence of the issue.
The maximum that can be obtained without modifications is the “Normal” signal from relay K1.
The game is not worth the candle. Most likely there is a PIC controller with limited resources and there is most likely no external interface.
The simplest solution (but expensive) is to buy another controller that has the required external interface.
OR make another controller and program it yourself. But I suspect that this is too difficult a task in this case.
