Motorized Screen


I have a motorised projector screen, which is currently operated with a 3-way switch (up, stop and down).
It is a Chinese one, I-view model E300, I found it installed.
I’d like to operate it using my Crestron rely (wire connection).
Is it possible to control it via PCB, or any other way. It has also remote Controller.

Any suggestions is highly appropriated!
