These DIP switches define internal control parameters for fan speed, model code, and auto-restart behavior.
Note: SW1 settings are factory-defined for each model and must not be changed on-site.
(1) SW1 Setting – Factory Model Configuration
1-1 Fan Speed Setting
Determines the preset fan performance curve for each indoor unit model.
| Model | SW1-1 | SW1-2 |
|---|---|---|
| AS7 | OFF | OFF |
| AS9 | ON | OFF |
| AS12 | OFF | ON |
| AS14 | ON | ON |
1-2 Model Code Setting
Defines internal model identity for correct PCB recognition.
| Model | SW1-3 | SW1-4 |
|---|---|---|
| AS7 | OFF | OFF |
| AS9 | ON | OFF |
| AS12 | OFF | ON |
| AS14 | ON | ON |
(2) SW2 Setting – Functional Adjustments
2-1 DIP SW 2-1 and 2-2
Both switches are forbidden and must remain OFF (factory default).
2-2 Auto Restart Setting
Enables automatic operation resumption following a power interruption.
| Switch | Setting | Function |
|---|---|---|
| SW2-3 | OFF | Auto restart invalid (factory) |
| SW2-3 | ON | Auto restart valid |
2-3 DIP SW 2-4
Setting forbidden. Must remain OFF (factory).
Operational Notes
SW1 group defines model-specific parameters—do not adjust during installation or servicing.
SW2-3 may be toggled ON if auto-restart is required for sites prone to power loss.
All other switches must remain OFF unless directed by manufacturer service documentation.
