New guy here, I've been contracted by a company to fix a botched VRF install, besides multiple leaks I've already found they daisy chained the communications wire incorrectly instead of indoor unit to indoor unit they ran all indoor units to the condenser. All of the wires were ran under ground and the house is nearing its final inspection and they cannot not run new wire.

My question is will the below set up work. I am unable to test the system as is due to the fact that they will not have power to the building for another two weeks.


IDU 1 --- Condenser --- IDU 2


This system is a part of the S series M/N PUMY-P60NKMU
