Precautions
1. A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
2. For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3. All transmission wiring except for the remote controller wiring is
polarized and must match the terminal symbol.
4. In case of group control, perform the remote controller wiring to
the master unit when connecting to the simultaneous operation
system (wiring to the slave unit is unnecessary).
5. When controlling the simultaneous operation system with
2 remote controllers, connect it to the master unit (wiring to the
slave unit is unnecessary).
6. Be sure to connect the wiring to the master unit when combining
with a simultaneous operating multi-type in group control.
7. Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.
Field setting
Field setting must be made on the remote controller in function of the
installation condition.

Setting can be made by changing the "Mode number", "First
code No." and "Second code No.".
 For setting and operation, refer to the "Field settings" in the
installation manual of the remote controller.

Note 1 : Setting is carried out in the group mode, however, if the mode number inside parentheses is selected,
indoor units can also be set individually.
Note 2 : Factory settings of the Second code No. are marked in grey backgrounds.
Note 3 : Only use in combination with optional remote sensor or when setting 10-2-03 is used.
Note 4 : If group control is selected and remote control sensor is to be used, then set 10-6-02 & 10-2-03.
Note 5 : If setting 10-6-02 + 10-2-01 or 10-2-02 or 10-2-03 are set at the same time, then setting 10-2-01,
10-2-02 or 10-2-03 have priority.
Note 6 : If setting 10-6-01 + 10-2-01 or 10-2-02 or 10-2-03 are set at the same time, then setting for group
connection, 10-6-01 has priority and for individual connection, 10-2-01, 10-2-02 or 10-2-03 have priority.
