1. Uvod
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. Varnostne informacije
Please read this section carefully before installation or operation to ensure safe and proper use of the device.
- Pred kakršno koli namestitvijo ali vzdrževanjem izklopite napajanje.
- Ensure the power supply matches the controller's specifications (12V AC ±10%).
- Vsa napeljava mora biti v skladu z lokalnimi in nacionalnimi električnimi predpisi.
- Naprave ne izpostavljajte prekomerni vlagi ali ekstremnim temperaturam zunaj njenega delovnega območja.
- Namestitev in ožičenje naj izvaja samo usposobljeno osebje.

4. Namestitev in ožičenje
The controller is designed for panel mounting. Ensure adequate ventilation and avoid locations subject to strong vibrations, corrosive gases, or excessive dust.
4.1 Montaža
Mount the controller into a standard panel cutout. Secure it using appropriate mounting hardware.
4.2 Shema ožičenja
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 sonda: 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.
- Druge povezave: 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. Delovanje
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 Zaslon
The front display shows the current temperature measured by the NTC probe or various parameter values during programming.
5.2 gumbi
The controller typically includes buttons for:
- Set: To enter parameter setting mode or confirm a value.
- Puščice gor/dol: To navigate through parameters or adjust values.
- Function/Auxiliary: For specific functions like manual defrost or viewing stanje.
Consult the full programming manual for detailed instructions on setting temperature setpoints, differentials, and other control parameters relevant to your air conditioning application.
6. Vzdrževanje
Redno vzdrževanje zagotavlja optimalno delovanje in dolgo življenjsko dobo vašega krmilnika.
- Čiščenje: Periodically clean the front panel with a soft, damp krpo. Ne uporabljajte abrazivnih čistil ali topil.
- Povezave: Letno preverite vse električne povezave glede tesnosti in znakov korozije.
- Sonda: Ensure the NTC probe is clean and properly positioned for accurate temperature readings.
- Prezračevanje: Verify that the controller's ventilation openings are not obstructed.
7. Odpravljanje težav
Ta razdelek obravnava pogoste težave, na katere lahko naletite. Za bolj zapletene težave se obrnite na tehnično podporo.
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Krmilnik se ne vklopi | No power supply; incorrect wiring; blown fuse (internal/external) | Check 12V AC power supply; verify wiring connections; inspect fuses. |
| Netočno odčitavanje temperature | Faulty NTC probe; probe incorrectly positioned; wiring issue to probe | Check probe connection; reposition probe; replace probe if damaged. |
| Outputs not switching | Incorrect parameter settings; faulty relay; wiring issue to load | Review setpoint and differential settings; check load wiring; contact support if relay is suspected faulty. |
| Zaslon prikazuje kodo napake | Sensor error; internal fault | Consult the full Eliwell manual for specific error code meanings and solutions. |
8. Uporabniški nasveti
- 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.
