(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 control communication wire separately from the power supply wire or wires of other
electric devices (AC220V or higher).
(10) 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 control. (This is displayed when the unit is in trouble and under the centralized control, regardless of ON/OFF)
Note (1) Time setting for the filter sign can be made as shown below using the indoor function of wired remote control “FILTER SIGN SET”. (It is set at 1 at the
shipping from factory.)

(11) Outline of automatic operation
(a)
Determination of operation mode
The unit checks the indoor air temperature and the outdoor air temperature, determines the operation mode, and then
begins in the automatic operation.
(b)
The unit checks the temperature every hour after the start of operation and, if the result of check is not same as the previous
operation mode, changes the operation mode.
(i)
If the setting temperature is changed with the remote control, the operation mode is judged immediately.
(ii)
When both the indoor and the outdoor air temperatures are in the range “A”, cooling or heating is switched depending
on the difference between the setting temperature and the indoor air temperature.
(iii)
When the operation mode has been judged following the change of setting temperature with the remote control, the
hourly judgment of operation mode is cancelled.
(c)
When the unit is started again within one hour after the stop of automatic operation or when the automatic operation is
selected during heating or cooling operation, the unit is operated in the previous operation mode.
(12) Frost prevention control
