4. Fifi sori ẹrọ ati Wiring
The controller is designed for panel mounting. Ensure adequate ventilation and avoid locations subject to strong vibrations, corrosive gases, or excessive dust.
4.1 Iṣagbesori
Mount the controller into a standard panel cutout. Secure it using appropriate mounting hardware.
4.2 Wiring aworan atọka
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~'.
- Iwadi NTC: 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.
- Awọn isopọ miiran: 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. Isẹ
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 Ifihan
The front display shows the current temperature measured by the NTC probe or various parameter values during programming.
5.2 Awọn bọtini
The controller typically includes buttons for:
- Ṣeto: To enter parameter setting mode or confirm a value.
- Awọn itọka oke/isalẹ: To navigate through parameters or adjust values.
- Function/Auxiliary: For specific functions like manual defrost or viewipo ipo.
Consult the full programming manual for detailed instructions on setting temperature setpoints, differentials, and other control parameters relevant to your air conditioning application.

8. Awọn imọran olumulo
- Always ensure the NTC probe is placed in a location that accurately reflects the temperature you wish to control.
- For critical applications, consider using an external temperature monitor to cross-verify readings.
- Keep a record of your parameter settings for quick reference or if a reset is needed.
