2.4.5 Considerations depending on the outdoor and indoor units


Simultaneous operation for UTOPIA series
In case of using PC-ARF, PC-ART, PC-ARH or PC-LH3(A/B) with H-LINK II units UTOPIA simultaneous operation (Twin,
Triple, Quad), remote control cable between indoor units can be removed.
However, the following limitations exist.
1 PC-ARF, PC-ART, PC-ARH or PC-LH3(A/B) cannot be installed as a second remote control in the same unit as sub
controller. (But they can be installed as main controller.)
2 Optional Function setting for "remote ON/OFF", "power supply ON/OFF" and "controller not available mode" can be set
only at the Master unit.
3 It is not permitted to group indoor units from different outdoor units in the same remote control. If grouping indoor units
from different outdoor units, an interconnection cable must be installed between indoor units from different outdoor
units.
4 In case of central control, only the Indoor unit with remote control connected can be the Master unit. Indoor Unit address
cannot be set from remote control when no cable option is used.

Combination with indoor units
• When using the controllers PC-ARF, PC-ART, PC-ARH, HARC-BX E (A/B) or the receiver kits PC-ALHZ(F) with RPK
models, the RPK indoor unit must be set as "Wired" by means of the SW2 of the PCB2. Otherwise, the operation is not
available.
• When using two remote controls in one indoor unit, ensure that one of them is set as "Master" and the other one is set
as "Slave".
