4. Produktlayout og kontroller

Image: Diagram illustrating the front and back panels of the STC-3031 model. The front panel shows the dual real-time displays, 'Out' and 'Set' indicators, 'Set' key, 'Up' key, 'Shutdown' key, and 'Down' key. The back panel indicates 'Exportation' and 'Sensor' connection ports.

Kontrol på frontpanelet:

• Realtidsvisning: Shows current humidity readings.
• Output Light (Out): Indicates when the output relay is active.
• Set Light (Set): Indicates when the device is in setting mode.
• Set Key (S): Used to enter and confirm parameter settings.
• Op-tast (▲): Bruges til at øge værdier eller navigere i menupunkter.
• Ned-tast (▼): Bruges til at mindske værdier eller navigere i menupunkter.
• Shutdown Key (Power Symbol): Used to power on/off or exit setting mode.

Bagpaneltilslutninger:

• Exportation Ports: Terminals for connecting external devices (e.g., humidifiers, dehumidifiers, pumps).
• Sensorporte: Terminals for connecting the soil humidity sensor cables.

5. Opsætning og installation

1. Montering: Install the controller into a panel cutout of 71x29mm. Ensure adequate ventilation around the unit.
2. Ledningsstrøm: Connect the AC110-220V power supply to the designated power input terminals on the back of the controller. For STC-3031, ensure the correct DC12V/DC24V/AC110-220V input is used based on your model.
3. Tilslutning af sensorer: Connect the soil humidity sensor cable(s) to the 'Sensor' ports on the back panel. Ensure a secure connection.
   • STC-3029: Connect one sensor.
   • STC-3030/STC-3031: Connect two sensors.
4. Connecting Output Devices: Connect your external humidity control devices (e.g., humidifier, dehumidifier, water pump) to the 'Exportation' ports. Ensure the total power consumption does not exceed the controller's maximum output power (1500W for most models, refer to specifications for STC-3031).
5. Sensorplacering: Insert the soil sensor probes into the soil at the desired depth and location for accurate moisture detection. Ensure the probes are fully in contact with the soil.
6. Første gang tændt: After all connections are secure, apply power to the controller. The display should light up, showing the current humidity reading.

Vigtig sikkerhedsbemærkning: All wiring should be performed by a qualified professional to prevent electrical hazards. Disconnect power before making any connections or disconnections.

6. Betjeningsvejledning

6.1. Tænd/sluk

Tryk på Sluk nøgle (power symbol) to turn the device on or off.

6.2. Viewing Current Humidity

Upon powering on, the large screen display will show the real-time humidity detected by the sensor(s).

6.3. Setting Humidity Parameters

1. Gå ind i indstillingstilstand: Tryk og hold på Set Key (S) for approximately 3 seconds until the 'Set' light illuminates and the display starts flashing.
2. Adjust Set Point: Brug Up Key (▲) og Down Key (▼) to adjust the desired humidity set point. This is the target humidity level you want to maintain.
3. Bekræft indstilling: Tryk på Set Key (S) again to confirm the value and move to the next parameter (if applicable) or exit setting mode.
4. Afslut indstillingstilstand: If no further parameters need adjustment, press the Sluk nøgle or wait for approximately 10 seconds for the device to automatically exit setting mode.

Note: For STC-3030 (dual-channel), you may have separate set points for each output channel. Refer to the specific model's detailed instructions for dual-channel configuration.

6.4. Calibration (Advanced)

If calibration is required, consult the full product manual or manufacturer's support. Typically, calibration involves adjusting an offset value to match a known reference humidity.

7. Vedligeholdelse

• Rensning: Regularly wipe the controller's display and casinmed en blød, tør klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
• Sensorpleje: Periodically inspect the soil sensors for dirt, debris, or corrosion. Gently clean the probes with water and a soft brush if necessary. Ensure they are dry before re-inserting into soil.
• Tilslutningskontrol: Annually check all electrical connections for tightness and signs of wear or corrosion.
• Miljøforhold: Ensure the controller is operated within its specified environmental limits (temperature, humidity) to prolong its lifespan.
