• Remove a two mounting screw, remove the control box

cover, and then connect the wires by following the procedure
given in the illustration.

10.4.8.

Settings

• All sets in the group which uses the same remote controller thermistor settings can be controlled by the same remote controller

thermistor.

• Up to a maximum of 16 indoor units can be connected at the time of group control. (Do not connect heat pump unit with cooling

only unit.)

• Indoor unit No. will be set automatically at the time of group control. However, which indoor unit uses which number is unknown.

Indoor unit No. is also possible to be set manually with DIP switches. Since manual address setting has priority to automatic
address setting. To perform automatic address settings after doing manual setting, turn off all DIP switches from No.1 to No.4,
and then stop the operation. Then press three switches such as [AIR SWING AUTO]. [MODE]. [A/C No.] at the same time. (Do
not use manual address setting and automatic address setting together.)

• Centralized control is possible for master unit and slave unit at the time of group control.

CONNECTING THE WIRES TO THE CONTROL BOX

Caution

Make sure that screws of the terminal are securely tight-
ened.

Do not operate the remote controller within 1 minute after turning on the power of the indoor unit.

When using group control with the standard type, at least 1 unit must be set at No.1 at the indoor unit.

Check the settings of the indoor unit in a case where there are no display at remote controller. If there is no problem to the settings, either
group control or standard type should be set at No.16 at the indoor unit before turning the power on again.
