e For use with 2 user interfaces
▪ Setting master unit (Cooling/Heating masterhood). In case of
group control, connect the user interface wiring directly to the
master unit. Do not connect user interfaces directly to slave units.
Slave units are restricted in their operation by the master unit (e.g.
1 outdoor unit does not allow for 1 indoor unit to run in cooling
operation while another runs in heating operation). For setting
using the user interface, refer to the manual or reference guide of
the user interface.
▪ 2 or more user interfaces: When using 2 or more user
interfaces, one must be
set to "MAIN" and the other to "SUB". For setting procedure see
the installation
and operation manual of the used user interface.
INFORMATION
In case of group control, it is not necessary to assign a
group address to the indoor unit. The group address is
automatically set when the power is turned on.
