1. Entwodiksyon
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. Enfòmasyon sou Sekirite
Please read this section carefully before installation or operation to ensure safe and proper use of the device.
- Dekonekte kouran an anvan ou fè nenpòt enstalasyon oswa antretyen.
- Ensure the power supply matches the controller's specifications (12V AC ±10%).
- Tout fil elektrik yo dwe konfòme yo ak kòd elektrik lokal ak nasyonal yo.
- Do not expose the device to excessive moisture or extreme temperatures outside its operating range.
- Se sèlman pèsonèl kalifye ki ta dwe fè enstalasyon ak fil elektrik.

4. Enstalasyon ak fil elektrik
The controller is designed for panel mounting. Ensure adequate ventilation and avoid locations subject to strong vibrations, corrosive gases, or excessive dust.
4.1 Montaj
Mount the controller into a standard panel cutout. Secure it using appropriate mounting hardware.
4.2 Dyagram fil elektrik
Refer to the diagram below for correct electrical connections. All connections must be made with the power supply disconnected.
- Alimantasyon (12V AC): Connect the 12V AC supply to the terminals marked 'N' and '12V~'.
- Sond 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.
- Lòt Koneksyon: 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. Operasyon
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 Montre
The front display shows the current temperature measured by the NTC probe or various parameter values during programming.
5.2 bouton
The controller typically includes buttons for:
- Mete: To enter parameter setting mode or confirm a value.
- Flèch anwo/desann: To navigate through parameters or adjust values.
- Function/Auxiliary: For specific functions like manual defrost or viewestati ing.
Consult the full programming manual for detailed instructions on setting temperature setpoints, differentials, and other control parameters relevant to your air conditioning application.
6. Antretyen
Regular maintenance ensures optimal performance and longevity of your controller.
- Netwayaj: Periodically clean the front panel with a soft, damp twal. Pa sèvi ak pwodui netwayaj abrazif oswa solvang.
- Koneksyon: Chak ane, tcheke tout koneksyon elektrik yo pou wè si yo sere epi si gen siy korozyon.
- Sonde: Ensure the NTC probe is clean and properly positioned for accurate temperature readings.
- Vantilasyon: Verify that the controller's ventilation openings are not obstructed.
