Connecting the Remote Controller — B, C, K, N, SB, S, TU, U only
Any standard 3-core cable operating at 12VAC with a cross-sectional area ranging from 0.3mm
!
to 0.75mm
2
and with a maximum length of 500 metres can be used.
When routing this cable, care should be taken to ensure that it is not in direct contact with mains
!
cable or routed in duct or conduit containing power cables.
Connect the terminals A, B and C on the remote controller with the terminals A, B and C on the
!
indoor unit terminal block, ensuring that the terminals are matched up correctly.
Full instructions on the setting and operation of this controller are included in the owner's manual,
!
supplied with the remote controller.
Group Control – B, C, K, N, SB, S, TU, U only
Up to 16 air conditioners can be controlled as a group using a single remote controller. (The
control circuit for each indoor unit originates at the outdoor unit from the incoming phase
!
connection marked L or L
throughout the group are derived from the same phase.)
!
No parts (except for the connecting cable) are required for group control.
Proceed with the power cable connections and with the wiring connections between the indoor
!
and outdoor units in exactly the same way as for individual air conditioner operation.
Connect the remote controller and the indoor unit in the following sequence:
1 Connect together the terminals A, B and C on both the remote controller and indoor unit No.1
ensuring that the terminals are matched up correctly;
2 Connect together terminals B and C on indoor units No.1 and No.2;
3 Connect together terminals B and C on indoor units No.2 and No.3;
4 Proceed in the same way to make the necessary connections up to indoor unit No.16;
Precautions
Use cables with a cross-sectional area of at least 0.75mm
!
length of 500 metres for the remote controller cable denotes the maximum length from the remote
controller to the furthest indoor unit.
5 Leave the (CN12) connector in unit No.1 (MCC-1361-01) but remove from
any further indoor units to prevent malfunction due to miswiring.
6 Set the rotary switch (SW01) position on each indoor unit (MCC-1361-01)
to a different number, starting with position 1 for unit No.1 which is connected to the remote
controller. This will also ensure that each unit will start up at a slightly different time therefore
ensuring no increase in start-up current.
