Note) [1] Don’t connect control wiring between indoor and outdoor units to several outdoor units.
(Outdoor unit to which control wiring between indoor and outdoor units is connected becomes the header outdoor unit automatically.)
[2]Don’t connect control wiring between indoor and outdoor units to other refrigerant system.
[3]Connect central control wiring to the header outdoor unit.
[4]When “1:1 model” is controlled by central control devices, “1:1 model” connection interface is necessary.
[5]In case of twin control on 1:1 model, connect “1:1 model” connection interface to the header indoor unit.
[6]Connect central control devices to central control wiring.
[7]Central control devices can be also connected to control wiring between indoor and outdoor units.
* In case of 1:1 model, address re-setup is needed from wired remote controller. (For details, refer to “3-2-10”).
2-3 Design of control wiring
1.All control wiring is 2-core and non-polarity wire.
2.Be sure to use shield wire for the following wiring to prevent noise trouble.
