Specifikationer

Opsætning og installation

Proper installation is crucial for the safe and effective operation of the STC-1000 temperature controller. Please follow the wiring diagram carefully.

Ledningsinstruktioner:

1. Strømforsyning: Connect the 110-220VAC power supply to terminals 1 (Live, L) and 2 (Neutral, N).
2. Sensortilslutning: Connect the temperature sensor to terminals 3 and 4. Ensure proper polarity if applicable, though typically NTC sensors are non-polar.
3. Varmeeffekt: For heating applications, connect the heating device to terminals 5 and 6. Terminal 5 is the common relay output, and terminal 6 is the normally open (NO) contact for heating.
4. Cooling Output: For cooling applications, connect the cooling device to terminals 7 and 8. Terminal 7 is the common relay output, and terminal 8 is the normally open (NO) contact for cooling.
5. Vigtig bemærkning: Strictly distinguish the interface of the relay, sensor, and power supply. Ensure the sensor probe and power wire are kept at a proper distance to avoid interference.

Panelintroduktion:

• Digital Display Window: Viser den aktuelt målte temperatur.
• Power Switch (⏻): Tænder eller slukker for enheden.
• Setting Button (S): Used to enter and confirm parameter settings.
• Increase Temperature Button (▲): Increases the set temperature value or navigates through menu options.
• Lower Temperature Button (▼): Decreases the set temperature value or navigates through menu options.

Indstilling af temperaturparametre:

1. Til View Indstil temperatur: Briefly press the 'S' button. The display will show the current set temperature. Press 'S' again or wait a few seconds to return to the current temperature display.
2. To Modify Set Temperature: Press and hold the 'S' button for approximately 3 seconds until the display flashes. Use the '▲' (up) and '▼' (down) buttons to adjust the desired temperature. Press 'S' again to confirm and save the new setting.
3. Accessing Advanced Settings (P0-P3): Press and hold the 'S' button for approximately 3 seconds. While the set temperature is flashing, press the 'S' button again to cycle through the parameter codes (P0, P1, P2, P3). Use '▲' and '▼' to adjust the values for each parameter. Press 'S' to confirm each parameter setting.

Fælles parametre:

• P0: Heating/Cooling Mode (C for Cooling, H for Heating).
• P1: Hysteresis Setting (Temperature difference for relay activation).
• P2: Upper Limit of Set Temperature.
• P3: Lower Limit of Set Temperature.

Opretholdelse

To ensure the longevity and accurate performance of your Walfront STC-1000 Digital Temperature Controller, follow these maintenance guidelines:

• Rensning: Regularly wipe the exterior of the controller with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the plastic casing eller display.
• Sensorpleje: Keep the temperature sensor clean and free from debris. Ensure it is not exposed to extreme physical stress or corrosive environments unless specifically designed for such conditions.
• Tilslutningstjek: Periodically inspect all wiring connections to ensure they remain secure. Loose connections can lead to inaccurate readings or device malfunction.
• Miljøforhold: Operate the controller within its specified environmental limits (temperature, humidity) to prevent damage. Avoid direct exposure to water or excessive dust.
• Sluk før vedligeholdelse: Always disconnect the power supply to the controller before performing any cleaning or inspection to prevent electrical shock.
