Hey guys, I recently moved into a townhouse that has 4 levels and decided to install a central vacuum. The builder had the rough in done, so I though that it is an easy job to finish it, however I ran into problems. The builder had a pipe and one low voltage wire (2 pairs) brought into the mechanical room, inside the garage. It looks like the other end of that wire terminated inside the inlet (#1) located inside the garage (same level). Inside the same garage inlet (#1), I found one more wire (2 pairs again) that look to terminate into the inlet from my second level (#2) (above the garage). Once I connected these wires inside inlet #1, I have working inlets in the garage and second floor. That being said, the next two levels are connected to each other via another 2 pairs wire, but not to the rest of the system. The piping is all good, I confirmed that I have suction on both levels (3 & 4) once the unit is running, but I cannot turn the unit on/off from the level 3 & 4. There is no other wire in those inlets (#3, #4). All inlets had the one pair connected to the outlet (black/green), while the other pair (red/yellow) was not used. I tied them all together (black and red together as one wire, and green and yellow as another wire), hoping that somehow the builder might have connected level 2 with either 3 or 4 via the other pair, but no luck. Are there any installers here, that might shine some light onto a practice that I am missing? Any other ideas that I should try before opening up walls and such to run wires? Thanks in advance
