(∗1) Switching is needed if the connection is previous Super Link.
Actual type of network connection (New or previous Super Link) depends on the models of indoor units and outdoor units, etc. Please contact the agency or the
Sales representative.
(∗2) When J1 is disconnected, the Center/Remote does not be set from this central control. Please disconnect if multiple central controls are installed and another
main central control exists.
When J1 is disconnected, data is sent for the blower only during demand input (nothing is performed when SW6 is off) and for stop only during emergency stop input.
NOTE
Do not connect the power supply wire to another terminal.
Making the wrong connection can result in damage or burning of
electrical parts and is extremely dangerous.
Please check the wires again before turning on the power supply.

6 Setting the Control Target Units
It is possible to change the setting as follows by settings of the PCB switches SW1 to SW10, J1, J2, and J3 on the central control.
Please change the control on site as necessary. It is recommended to change the setting by using a precise driver.
Make the settings for the units to be controlled by the central control.
For the setting procedure, see the user’s manual attached to the central contrl.
At shipping, none of the units are set as target units for control, and so the units to be controlled by this central control
must be set as control target units.
Three types of settings are available.
① Units are selected as control targets for central control and controlled
as a group
② Units are selected as control targets for central control but not grouped
③ Units are not selected as control targets for central control
(or units will be controlled by another central control)
Be sure to set the current time. This is needed for the program settings and error history display.
Turn on the power and press the three buttons (MENU, RESET, GROUP No. 10) at once more than five minutes, that can
initialize the setting contents.

Group control when using multiple units
This central control can control up to 64 target units
(up to 48 units when using the previous Super Link
setting). Multiple central controls must be installed to
control 65 or more air conditioner units.
When connecting multiple central controls on a single
network, any group settings can be made for each
central control.

(∗1)
Please connect to ground for signal wire and power supply wire.
(∗2) The selected relay obtained at the site should have the following specifications: rated voltage
of DC 12V and maximum power consumption of DC 0.9W or less (80mA or less)
(∗3) The selected relay obtained at the site should have the following specifications: Non-voltage "a"
contact input and capable of withstanding a minimum applied load of DC 12V and 10mA or less.
The DO and DI terminals are polar.
Do not connect three or more wires to the same terminal.
