Each successive unit will respond at one-second
1 2
intervals following the order of the group address
when the remote controller is operated.
0800_M_I
When using multiple remote controllers (up to 2 of
them can be used), one is the main remote controller
and the other is the sub-remote controller.
To set up a sub-remote controller, turn its remote
control address switch (RCU. ADR) located on its
PCB from OFF to ON (OFF: when shipped from
factory).

Example.1 In the ECO multi system, group control
extending over tubing systems be
comes impossible to set, giving rise to
indoor units which cannot operate.
While group 4 is in heating operation, if later group 3
begins cooling operation, indoor units 1, 2 of group 3
can be operated, but the indoor units 3-6 of group 4
cannot operate.
