I apologize if this has been asked before, or if it isn't allowed here. I own a window cleaning company and am trying to automate my setup. I recently ordered this PCB that allows me to flush the system for 18 seconds before filling my water tank while I'm working. ​The problem is, I can't find the seller to ask for a setup video. The only resource I could find is a wiring guide, and I just can't figure it out. I would greatly appreciate any help or feedback!
