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
(change-over 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.
7.6.2 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
(change-over under centralised control) of
all slave user interfaces connected to the same outdoor unit flashes.
