4. Орнотуу жана зымдар
The controller is designed for panel mounting. Ensure adequate ventilation and avoid locations subject to strong vibrations, corrosive gases, or excessive dust.
4.1 Монтаждоо
Mount the controller into a standard panel cutout. Secure it using appropriate mounting hardware.
4.2 Электр өткөргүч схемасы
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 иликтөөсү: 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.
- Башка байланыштар: 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. Операция
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 Дисплей
The front display shows the current temperature measured by the NTC probe or various parameter values during programming.
5.2 баскычтар
The controller typically includes buttons for:
- Орнотуу: To enter parameter setting mode or confirm a value.
- Өйдө/төмөн жебелер: To navigate through parameters or adjust values.
- Function/Auxiliary: For specific functions like manual defrost or viewабалы.
Consult the full programming manual for detailed instructions on setting temperature setpoints, differentials, and other control parameters relevant to your air conditioning application.
6. Техникалык тейлөө
Regular maintenance ensures optimal performance and longevity of your controller.
- Тазалоо: Алдыңкы панелди мезгил-мезгили менен жумшак, d менен тазалап туруңузamp кездеме. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
- Байланыштары: Жыл сайын бардык электр туташууларынын бекемдигин жана дат басуу белгилерин текшерип туруңуз.
- Текшерүү: Ensure the NTC probe is clean and properly positioned for accurate temperature readings.
- Вентиляция: Verify that the controller's ventilation openings are not obstructed.
