Checking Rotary Switch and DIP Switch Settings

The following diagram indicates the factory settings of DSWs on PCBs in the indoor and outdoor units.
When simultaneous operation control of multiple units or room thermostat control is operated, the DSW
setting will be different as shown below.
(1) Outdoor Unit (Factory Setting)
Refer to the Service Manual for Outdoor Unit.
(2) Indoor Unit (Factory Setting)
The positions of the DIP switches on the PCB are shown in the figure below. Turn OFF all power
supplies before setting.
Without turning OFF all power supplies, the switches do not work and the settings are invalid.
The "n" mark indicates the position of DIP switches.
● Ducted High Static
● Ducted Medium Static and Slim

DIP Switch Settings
(1) Turn OFF the power supply of the indoor unit and the outdoor unit before DIP switch setting. Not doing
so makes the setting invalid.
(2) Factory settings for DSW6 and RSW1 are set to "0". If connecting the indoor unit to H-LINK II
supporting the outdoor unit without setting any DIP switches, auto-address setting is performed by the
wired controller.
(3) Auto-Address Setting by Wired Controller
The address numbering is started from "0" by the auto-address function when the wired controller is
connected to H-LINK II.
