<Sequential Start Timer>
The refrigerant address also acts as a sequential start timer (one-second interval) to suppress the rush current.
The initial refrigerant address is 0. In this case, the sequential start timer is “0”, and the delay time is * 0 to 9.
Depending on the combination of the No. 3 to 6 switch settings, the units can be sequentially started at one-second intervals be-
tween 1 to 15 (delay time is 10 to 2).
* Differs according to the remote controller operation timing.
(Example) Sequential start timer 12 = 8 +

<Confirming the outdoor unit address>
To determine which outdoor unit corresponds to the designated refrigerant address, designate the refrigerant address with the
self-diagnosis mode. The designated outdoor fan will run intermittently.
With the initial setting (refrigerant address 0), the sequential start timer is “0” and the delay time is * 0 to 9.
<Work procedures>
• Connect the remote controller to one of the indoor units, and connect each refrigerant system with a crossover wire.
Always wire from the indoor unit.
• Set the refrigerant address for each outdoor unit, and turn the power ON.
Set the refrigerant address before turning the power ON.
* The power for the remote controller is supplied from the address 00 indoor unit. (LED2 on the indoor control board will light.)
<Outdoor unit address setting>
• For group control, an address must be set for each outdoor unit.
• To set addresses to outdoor units, use the DIP switch SW1 (3-6) provided on each outdoor control board (Initial setting: All are
set to "OFF".)
• Address setting by SW1 is as follows.

To find the location of an outdoor unit with a specific refrigerant address, specify the address in self-diagnosis mode. The out

door unit will operate intermittently.
