Multi-Split Communication Wiring Check
The FlexFit Multi and Arctic multi systems are capable of performing a self-test to check
communication wiring between the outdoor to the indoor units. This is a crucial step when performing
start-up on a system as well as performing checks during a service call. It allows you to confirm that
the wiring matches with the associated refrigerant lines for a given circuit.
