Installation and operation manual

Summary of field settings

■

When using wireless remote controllers it is necessary to use
address setting. Refer to the installation manual attached to the
wireless remote controller for the setting instructions.

Control by 2 Remote Controllers (Controlling 1 indoor
unit by 2 remote controllers)

When using 2 remote controllers, one must be set to "MAIN" and the
other to "SUB".

Main/sub changeover

Insert a wedge-head screwdriver into the recess between the
upper and lower part of the remote controller and, working from
the 2 positions, pry off the upper part.

(See figure 18)

(The remote controller PC board is attached to the upper part of
the remote controller.)

Turn the main/sub changeover switch on one of the two remote
controller PC boards to "S".

(See figure 19)

(Leave the switch of the other remote controller set to "M".)

Computerised control (forced off and on/off operation)

Wire specifications and how to perform wiring.

•

Connect input from outside to terminals T1 and T2 of the terminal
block (remote controller to transmission wiring).

See

figure 17

Actuation

•

The following table explains "forced off" and "on/off operations" in
response to input A.

How to select forced off and on/off operation

•

Turn the power on and then use the remote controller to select
operation.

•

Set the remote controller to the field set mode. For details, refer to
the chapter "How to set in the field", in the remote controller
manual.

•

When in the field set mode, select mode No. 12, then set the first
code (switch) No. to "1". Then set second code (position) No. to
"01" for forced off and to "02" for on/off operation. (forced off at
factory set.)

(See figure 16)

Centralized control

For centralized control, it is necessary to designate the group No. For
details, refer to the manual of each optional controller for centralized
control.

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 remocon 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
