Can you show a video how to Vaccum down the systems when 4 zones using a branch box

@warrior90 I noticed no one ever responded. There is nothing different to do on a residential branch box system compared to any other split system you vacuum on the regular basis. The Expansion Valves, for indoor unit metering, are located in the branch box and they can never fully close. So there is no need energize equipment and do anything special to make them open up.

Other than the address settings, does switch 5(S5) in the outdoor unit, require changes for proper monitoring?

What if there is no branch box? Just 1 outdoor unit and 1 indoor unit?

these MXZ outdoor units need at least 2 indoor units i believe
