5. Betjeningsvejledning

5.1 Grundlæggende betjening

  • Tænd/sluk: Tryk på tænd / sluk-knappen () for at tænde eller slukke for enheden.
  • View Aktuel temperatur: The main display shows the current measured temperature.
  • Indstil temperatur: Press the 'Set' button to enter temperature setting mode. Use the Up () og ned () buttons to adjust the desired temperature. Press 'Set' again to confirm and exit.

5.2 Parameter Settings (F-Codes)

To access advanced parameters (F-codes), press and hold the 'Set' button for approximately 3 seconds until 'F0' appears. Use the Up () og ned () buttons to navigate through the F-codes (F0, F1, F2, F3, F4, F5). Press 'Set' to view or modify the value of a selected F-code. Press 'Set' again to save changes and move to the next parameter, or press the power button to exit without saving.

  • F0: Temperature Control Mode (0=Refrigeration, 1=Heating)
  • F1: Temperature Hysteresis (Differential)
  • F2: Alarmgrænse for høj temperatur
  • F3: Lav temperatur alarmgrænse
  • F4: Compressor Delay Time (in minutes)
  • F5: Temperature Correction Value

5.3 Visual Guide: Setting Parameters

Video 5.1: This video demonstrates how to access and adjust the F-code parameters on the Walfront STC-200 Digital Temperature Controller. It shows the sequence of button presses to enter the setting menu, navigate through F0 to F5, and modify their values, such as setting the temperature control mode or compressor delay.

6. Vedligeholdelse

  • Rensning: Regularly wipe the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
  • Sensorpleje: Ensure the temperature sensor is clean and free from debris. Avoid bending or damaging the sensor cable.
  • Miljøforhold: Operate the controller within the specified environmental temperature and humidity ranges to ensure longevity.

7. Fejlfinding

ProblemMulig årsagLøsning
Skærmen er tomNo power supply; Incorrect wiring; Unit failure.Check power connection (220VAC). Verify wiring according to diagram. If problem persists, contact support.
"E1" or "HHH" error on displaySensor fault (open circuit, short circuit); Temperature exceeds range.Check sensor connection and integrity. Ensure operating temperature is within -40°C to 99°C. Replace sensor if damaged.
Temperaturaflæsningen er unøjagtigSensor placement; Need for calibration.Relocate sensor to a more representative area. Use F5 parameter to apply temperature correction.
Controller not switching loadIncorrect temperature setting; Relay failure; Load wiring issue.Verify set temperature and hysteresis. Check load wiring (Terminals 1, 2, 3). Ensure F0 mode is correctly set (Refrigeration/Heating).
