5. Enstriksyon Enstalasyon

The DIGITEN DHC312 is designed for plug-and-play convenience. Follow these steps for initial setup:

1. Plasman: Position the main controller unit in a stable location.
2. Koneksyon Capteur: Ensure the humidity sensor is securely connected to the main controller unit. Place the sensor probe in the environment where humidity needs to be monitored and controlled. Avoid placing it near direct airflow or heat sources for accurate readings.
3. Koneksyon pouvwa: Plug the controller's power plug into a standard electrical outlet (100-240VAC).
4. Appliance Connection:
   • For humidification, plug your humidifier into the outlet labeled "HUMIDIFICATION" on the dual-stage power strip.
   • For dehumidification, plug your dehumidifier or exhaust fan into the outlet labeled "DEHUMIDIFICATION".

   Enpòtan: Ensure your humidifier has an automatic restart function for seamless operation with this controller.

6. Operasyon Enstriksyon

The DHC312 features a clear digital display and intuitive buttons for easy operation.

6.1 Ekspozisyon souview

Imaj 6.1: Detaye view of the controller's LCD screen, indicating various display elements such as current temperature, current humidity, and set humidity.

• Mòd travay: Indicates whether the unit is in humidification or dehumidification mode.
• Tanperati aktyèl: Displays the real-time ambient temperature.
• Current Humidity: Shows the real-time ambient humidity percentage.
• Setting Humidity (SET): Displays the target humidity percentage ou te mete.
• Difference (DIFF): Indicates the humidity differential setting.
• Calibration (CA): Indicates if calibration is active.

6.2 Fikse Imidite Sib la

1. Peze a Up (▲) oswa Desann (▼) button to adjust the target humidity value (SET).
2. After setting the desired value, wait approximately 5 seconds. The controller will automatically save the setting and return to the normal display mode.

6.3 Advanced Settings (Temperature Unit, Difference, Calibration)

1. Long peze la SET button for 3 seconds until the °C or °F indicator flashes.
2. While the indicator is flashing, short press the SET button to cycle through the advanced settings: Temperature Unit (°C/°F), Difference (DIFF), and Calibration (CA).
3. Sèvi ak la Up (▲) oswa Desann (▼) buttons to adjust the value for the selected setting.
4. Long peze la SET button for 3 seconds to save the changes and exit the advanced settings menu.

6.4 Humidification and Dehumidification Logic

The controller operates based on the set humidity value and the difference (DIFF) setting:

• Imidifikasyon: The humidification outlet turns ON when the measured humidity is ≤ (Setting Value - DIFF). It turns OFF when the measured humidity is ≥ Setting Value.
• Dezumidifikasyon: The dehumidification outlet turns ON when the measured humidity is ≥ (Setting Value + DIFF). It turns OFF when the measured humidity is ≤ Setting Value.

7. Kalibrasyon

The DHC312 allows for humidity calibration to ensure accuracy. If you have a trusted reference hygrometer, you can adjust the controller's reading.

1. Access the advanced settings menu by long pressing the SET bouton pou 3 segonn.
2. Kout peze la SET button until 'CA' (Calibration) is displayed.
3. Sèvi ak la Up (▲) oswa Desann (▼) buttons to adjust the calibration value. This value will offset the measured humidity.
4. Long peze la SET bouton pou 3 segonn pou sove epi sòti.

NAN. Depanaj

If you encounter issues with your DIGITEN DHC312, refer to the following common problems and solutions:

9. Antretyen

To ensure the longevity and accurate performance of your DIGITEN DHC312 Humidity Controller, follow these maintenance guidelines:

• Netwayaj: Periodically wipe the main unit and display with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
• Swen Capteur: Keep the humidity sensor clean and free from dust, debris, or moisture buildup. Gently clean the sensor housing if necessary.
