I have a factory 'roller shutter" door which has a 440v 3 button switch.
press and release any of the buttons activates the switch.
up, down and stop buttons.

I want to add a remote control as well. so I opened the back of the switch to understand what functions need to be in the remote. I found 4 wires going to this switch assembly.

when I touch jump the up contacts the door opens and will not stop till opened all the way or one of the the wires of the stop button is removed "disconnected" from the back of the stop button.
Same with the down button.

which remote do I need for this task?

Many thx
