(c) In case of anomaly
a)
If any anomaly occurs on a unit in a group (a protective function operates), that unit stops with the anomalous
stop but any other normal units continue to run as they are.
b) Signal wiring procedure
Signal wiring between indoor and outdoor units should be made on each unit same as the normal wiring. For
the group control, lay connect with sires wiring between rooms using terminal blocks (X, Y) of interface kit.
Connect the remote controller communication wire separately from the power supply wire or wires of other
electric devices (AC220V or higher).
(11) Filter sign
As the operation time (Total ON time of ON/OFF switch) accumulates to 180 hours (1), “Filter cleaning” is displayed on the
remote controller. (This is displayed when the unit is in trouble and under the centralized control, regardless of ON/OFF)
