System Control
System control refers to the link wiring connection
for control of simultaneous-operation multi
systems, group control,
and mainsub remote controller control.
Single type and simultaneous-operation multi
system
Basic wiring diagram 1
Simultaneous-operation multi system
Up to 2 (Twin) indoor units can be connected
to 1 outdoor unit for operation.
(However, coordinate the outdoor unit capacity
and the total capacity of the indoor units.)
(It is not possible to connect individual remote
controllers for independent operation.)
Group control (when a central control device is not used)
Basic wiring diagram 2
Simultaneous-operation multi system
Up to 2 (Twin) indoor units can be connected to 1 outdoor unit for operation.
(However, coordinate the outdoor unit capacity and the total capacity of the indoor units.)
(It is not possible to connect individual remote controllers for independent operation.)
A maximum of 8 indoor units can be connected to 1 remote controller.
When 2 indoor units are connected to each outdoor unit in the refrigerant system, set the system address
(refrigerant tubing system address) before turning on the remote power switch.
(Refer to section “Setting the outdoor unit system addresses”.)
(Set using the system address rotary switch on the outdoor unit control PCB.)
Be careful to avoid miswiring when connecting
the wires. (Miswiring will damage the units.)
