1. 서론
This manual provides detailed instructions for the installation, operation, and maintenance of the ELIWELL ST544 and ST544/C NTC Temperature Controllers. These controllers are designed for precise temperature management, particularly in air conditioning applications, and operate on a 12V AC supply.
2. 안전 정보
Please read this section carefully before installation or operation to ensure safe and proper use of the device.
- 설치 또는 유지보수 작업을 하기 전에 전원을 차단하십시오.
- Ensure the power supply matches the controller's specifications (12V AC ±10%).
- 모든 배선은 지역 및 국가 전기 규정을 준수해야 합니다.
- 장치를 작동 범위를 벗어난 과도한 습기나 극한 온도에 노출시키지 마십시오.
- 자격을 갖춘 인력만이 설치 및 배선 작업을 수행해야 합니다.

4. 설치 및 배선
The controller is designed for panel mounting. Ensure adequate ventilation and avoid locations subject to strong vibrations, corrosive gases, or excessive dust.
4.1 장착
Mount the controller into a standard panel cutout. Secure it using appropriate mounting hardware.
4.2 배선도
Refer to the diagram below for correct electrical connections. All connections must be made with the power supply disconnected.
- Power Supply (12V AC): Connect the 12V AC supply to the terminals marked 'N' and '12V~'.
- NTC 프로브: Connect the NTC temperature probe to the designated terminals.
- Outputs (DO1, DO2, TC1, DO3, DO4): These are relay outputs, rated at 2A 250V~. Connect your controlled devices (e.g., compressors, fans, heaters) to these terminals as per your application's requirements. 'N' terminals are common for some outputs.
- 기타 연결: Terminals like IDS, ID2, ID1, KEYB, AO3, AO2 are likely for digital inputs, communication, or auxiliary outputs. Refer to the full product datasheet for detailed functionality of these specific terminals if required.
5. 운영
The ST544 controller features a digital display and buttons for setting parameters and monitoring temperature. Specific operational details, including parameter codes and navigation, are typically found in the comprehensive programming manual for Eliwell controllers. This section provides general guidance.
5.1 디스플레이
The front display shows the current temperature measured by the NTC probe or various parameter values during programming.
5.2개의 버튼
The controller typically includes buttons for:
- 세트: To enter parameter setting mode or confirm a value.
- 위/아래 화살표: To navigate through parameters or adjust values.
- Function/Auxiliary: For specific functions like manual defrost or view상태.
Consult the full programming manual for detailed instructions on setting temperature setpoints, differentials, and other control parameters relevant to your air conditioning application.
6. 유지관리
Regular maintenance ensures optimal performance and longevity of your controller.
- 청소: 전면 패널을 주기적으로 부드러운 천으로 닦아주세요.amp 천. 연마성 세척제나 용매를 사용하지 마십시오.
- 사이: 매년 모든 전기 연결부의 조임 상태와 부식 여부를 점검하십시오.
- 조사: Ensure the NTC probe is clean and properly positioned for accurate temperature readings.
- 통풍: Verify that the controller's ventilation openings are not obstructed.
