controller
• There are two types of remote controllers: wired type and
wireless type.
• Simultaneous twin, triple and quad units are counted as one
unit and the indoor units can be operated or stopped simul-
taneously.
• An individual twin is counted as two units and the indoor
units can be operated independently. Each can perform a
different operation. For example, one unit can be used for
cooling while another is used for heating.

• Up to two remote controller can be connected to one group.
• Simultaneously twin, triple and quad units are counted as
one group.
• The operating control is the most recent command (last
entered priority).
B. Two remote con-
troller operation
• Wired remote con-
troller
• Wireless remote
controller
• The remote controller is connected and the address for
each outdoor unit is set so that a group of up to 16 units can
be started sequentially.
• Simultaneous twin, triple and quad units are counted as one
unit.
• One group can operate in the same mode but the on/off
operation of the thermostat is performed independently by
each outdoor unit.
C. 1 remote controller
group operation
• Wired remote con-
troller
• This can be set by using the function selection from the
remote controller.
