The remote controller wire is connected to CITY MULTI System (C type or later).
(In case of CITY MULTI System)
Group 1 Group 2 Group 3
NOTE: With group operation with a different cooling system, wire only the MA remote controller wiring terminal
block (TB15). Do not wire the indoor/outdoor transmission terminal block (TB5).
1 Wiring from signal receiving unit.
· Connected to MA remote controller wiring terminal block (TB15) on the indoor unit. (The terminal block has
no polarities.)
2 With group operation (group 3 and group 4 above).
· After wiring the MA remote controller wiring terminal block (TB15) on the group operation indoor unit, connect to the
indoor unit with the lowest address within the group.
3 The signal receiving unit and the MA remote controller may be used together (group 4 above).
· Set the MA remote controller as “Main”, and the signal receiving unit as “Sub”.
· When other types of remote controllers are used, refer to section “ 7 Possible Combinations of Signal Receiving
Units and Remote Controllers ”.
∗ See the installation manual supplied with the outdoor unit for details of setting up indoor (IC) and outdoor (OC) units.
∗ See the relevant equipment manual for details of setting up the central controller and transmission line power supply
unit.

Replace CN41
with CN40.
Leave CN41 as it is.
NOTE:
• No power supply lines are shown and only the trans-
mission lines are shown in the above wiring example.
• Provide shield grounding of M-NET transmission line
at one arbitrary point.
A main remote controller and a sub remote con-
troller can be connected to each group.
