J-Series External Contact Controller
DIP switch settings, factory defaults and external control reference
This controller allows external contact signal operation for J-Series systems, including remote ON/OFF, mode switching and parameter control.
DIP Switch Settings and Factory Defaults
| Switch | Function | Factory Setting |
|---|---|---|
| SW1-1 | MODE setting | OFF |
| SW1-3 | Delay-time setting (1 minute delay on mode change) | OFF |
| SW1-4 | Forbidden | ON |
| SW1-5-6 | Not used | OFF |
| SW2-1-5 | Not used | OFF |
| SW2-6 | Operation mode setting of parameter setting 1 (P1) | OFF |
| SW3-5 | Setting contact input of SW1 at MODE 0 | OFF |
| SW3-6 | Enables input when switched to P1 or P2 during indoor unit operation | OFF |
| SW4-6 | Operation mode setting of parameter setting 2 (P2) | OFF |
| SW5-5 | Setting contact input of SW2 at MODE 0 | OFF |
| SW5-6 | Cannot be used | ON |
Important: Do not alter switches identified as Forbidden, Not used or Cannot be used unless specifically directed by the relevant service documentation.
Switch Position Reference
- The DIP switches are located inside the controller housing.
- Switches are grouped from SW1 to SW5 and correspond to operational modes and external control logic.
- Connect terminals as follows:
- SW1 / SW2: Signal inputs
- Common / Earth: Shared reference
- 1 - Red, 2 - White, 3 - Black: Wiring sequence
Key Notes
Mode Control: SW1 determines how the unit responds to external input signals.
Delay Function: Activating SW1-3 introduces a 1-minute delay before the mode change occurs.
Parameter Settings (P1 / P2): SW2-6 and SW4-6 configure the control logic for linked operational modes.
Compatibility: Intended for system integration with building management or remote operation setups.
