Esquema de cablejat
Proper wiring is crucial for the safe and correct operation of the device. Refer to the diagrams below for connection instructions.
Image: Two wiring diagrams for the STC-3018. The top diagram shows wiring for a load with an independent power supply, while the bottom diagram shows wiring for a load with the same power supply as the controller. Both diagrams indicate connections for power supply, sensor, and output.
Nota important: Strictly distinguish the interface of the relay/sensor and power supply. The sensor down-lead and power wire should be kept a proper distance apart to avoid interference.
Instruccions de funcionament
Setting Temperature Parameters
- Encès: Ensure the device is correctly wired and powered on. The dual LED displays will show the current temperature (PV) and the set temperature (SV).
- Configuració d'accés: Premeu el botó Set button once to enter the temperature setting mode. The SV display will flash.
- Ajustar la temperatura: Utilitza el Up (▲) i Avall (▼) buttons to adjust the desired set temperature (SV).
- Confirmeu la configuració: Premeu el botó Set button again to confirm the new setting and exit the setting mode. The device will now operate according to the new set temperature.
- Restablir: To reset the device, press the primer botó.
Conversió d'unitats de temperatura
The STC-3018 supports temperature unit conversion. Refer to the panel introduction image for the location of the temperature unit conversion light. Specific instructions for changing units (e.g., Celsius to Fahrenheit) are typically found in the full product manual or by holding the 'Set' button for an extended period to access advanced parameters. Please consult the manufacturer's website or contact support for detailed steps if needed.
Manteniment
- Neteja: Regularly wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Cura del sensor: Assegureu-vos que el sensor de temperatura estigui net i lliure de residus. Eviteu doblegar o danyar el cable del sensor.
- Condicions ambientals: Operate the controller within the specified ambient temperature and humidity ranges (0~60°C, 20%~85% relative humidity, no condensation) to ensure longevity.
- Comprovació de la connexió: Inspeccioneu periòdicament totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén. | No hi ha alimentació o cablejat incorrecte. | Comproveu les connexions d'alimentació i assegureu-vos que el volum sigui correctetage (12V/24V/110V-220VAC) is supplied. Verify wiring against the diagram. |
| La lectura de temperatura és inexacta. | Damaged or improperly connected sensor. Sensor not in optimal measuring position. | Inspect sensor for physical damage. Ensure sensor is securely connected. Reposition sensor to accurately measure the desired area. |
| Controller not switching heating/cooling. | Incorrect temperature settings. Output wiring issue. | Verify the set temperature (SV) and ensure it aligns with the desired operation (heating or cooling). Check the output wiring to the connected device. |
| La pantalla mostra el codi d'error. | Sensor fault or internal error. | Refer to the full product manual for specific error codes. Often indicates a sensor open circuit or short circuit. Replace sensor if faulty. |
