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.
(a) Switch
(*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

(11) Setting the control target units
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
/
Group setting
②
Units are selected as control targets for central control but not grouped
/
Individual setting
③
Units are not selected as control targets for central control
/
Not target units for 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 second, that can
initialize the setting contents.
c
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.
