Please consult your sales representative when two or more central remote controllers need to be
installed in one system.
• What is the central remote controller?
The central remote controller allows all the stored remote controller groups (the indoor units) to
be controlled from a remote location.
(Refer to “2-3. EXPLANATION OF TERMS 1” for details about remote controller groups.)
• Three functions of the central remote controller
• CENTRAL CONTROL
The central control provides management of the remote controller groups (the indoor units).
This includes placing restrictions on the standard remote controllers or performing memory op-
eration for easily reproducing operating conditions that have been saved.
• OPERATION CONTROL
The operation control provides a controlled operation (such as the to stop operation) of the stored
remote controller groups (the indoor units) in the same manner as the standard remote control-
ler.
• TIMER CONTROL
The timer control allows the starting and stopping of stored remote controller groups and indoor
units through the timer functions in the central remote controller. These timer functions include:
the off timer, on timer 1, on timer 2 and weekly timer.
