Procedure for checking indoor-outdoor unit transmission wiring for broken wires
Turn OFF the power supply to all equipment, short circuit between the indoor-outdoor unit
terminal F1 and F2 in outdoor unit, and then conduct continuity checks between the
transmission wiring F1 and F2 of "Indoor Unit a" farthest from outdoor unit using a multimeter. If
there is continuity between the transmission wiring, the indoor-outdoor unit transmission wiring
has no broken wires in it.
If there is no continuity, the transmission wiring may have broken wires. With the indoor-outdoor
unit terminal of outdoor unit short circuited, identify the areas with continuity in the transmission
wiring of "Indoor Unit b", transmission wiring of "Indoor Unit c", and transmission wiring of
"Indoor Unit d" in the order described.
If the areas with continuity can be identified, there may be broken wires in places before those
areas.
