d User interface
When the system is installed as shown in the figure above, it is
necessary to – for each subsystem – designate one of the user
interfaces as the master user interface.
The displays of slave user interfaces show (changeover under
centralised control) and slave user interfaces automatically follow the
operation mode directed by the master user interface.
Only the master user interface can select heating or cooling mode
(cooling/heating masterhood).
6.5.2 To designate the master user interface
1 Press the operation mode selector button of the current master
user interface for 4 seconds. In case this procedure was not yet
performed, the procedure can be executed on the first user
interface operated.
Result: The display showing (changeover under
centralised control) of all slave user interfaces connected to the
same outdoor unit flashes.
2 Press the operation mode selector button of the controller that
you wish to designate as the master user interface.
Result: Designation is completed. This user interface is
designated as the master user interface and the display
showing (changeover under centralised control) vanishes.
The displays of other user interfaces show (changeover
under centralised control).
Refer to the operation manual of the user interface.
