5. Pokyny k nastavení
The DIGITEN DHC312 is designed for plug-and-play convenience. Follow these steps for initial setup:
- Umístění: Position the main controller unit in a stable location.
- Připojení senzoru: 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.
- Připojení napájení: Plug the controller's power plug into a standard electrical outlet (100-240VAC).
- Připojení spotřebiče:
- 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".
Důležité: Ensure your humidifier has an automatic restart function for seamless operation with this controller.

6. Návod k obsluze
The DHC312 features a clear digital display and intuitive buttons for easy operation.
6.1 Zobrazení nadview
Obrázek 6.1: Detailní view of the controller's LCD screen, indicating various display elements such as current temperature, current humidity, and set humidity.
- Pracovní režim: Indicates whether the unit is in humidification or dehumidification mode.
- Aktuální teplota: Displays the real-time ambient temperature.
- Aktuální vlhkost: Shows the real-time ambient humidity percentage.
- Setting Humidity (SET): Displays the target humidity percentage máte nastaveno.
- Difference (DIFF): Indicates the humidity differential setting.
- Calibration (CA): Indicates if calibration is active.
6.2 Nastavení cílové vlhkosti
- Stiskněte tlačítko Up (▲) nebo Dolů (▼) button to adjust the target humidity value (SET).
- 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)
- Dlouze stiskněte SOUBOR button for 3 seconds until the °C or °F indicator flashes.
- While the indicator is flashing, short press the SOUBOR button to cycle through the advanced settings: Temperature Unit (°C/°F), Difference (DIFF), and Calibration (CA).
- Použijte Up (▲) nebo Dolů (▼) buttons to adjust the value for the selected setting.
- Dlouze stiskněte SOUBOR 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:
- Zvlhčování: The humidification outlet turns ON when the measured humidity is ≤ (Setting Value - DIFF). It turns OFF when the measured humidity is ≥ Setting Value.
- Odvlhčování: The dehumidification outlet turns ON when the measured humidity is ≥ (Setting Value + DIFF). It turns OFF when the measured humidity is ≤ Setting Value.

7. Kalibrace
The DHC312 allows for humidity calibration to ensure accuracy. If you have a trusted reference hygrometer, you can adjust the controller's reading.
- Access the advanced settings menu by long pressing the SOUBOR tlačítko na 3 sekund.
- Krátce stiskněte SOUBOR button until 'CA' (Calibration) is displayed.
- Použijte Up (▲) nebo Dolů (▼) buttons to adjust the calibration value. This value will offset the measured humidity.
- Dlouze stiskněte SOUBOR tlačítko na 3 sekund pro uložení a ukončení.
8. Řešení problémů
If you encounter issues with your DIGITEN DHC312, refer to the following common problems and solutions:
| Problém | Možná příčina | Řešení |
|---|---|---|
| Displej ovladače je vypnutý. | Žádné napájení. | Check if the power plug is securely inserted into a live outlet. Verify the outlet is functioning. |
| Nepřesné údaje o vlhkosti. | Sensor dirty or improperly placed; calibration needed. | Clean the sensor gently. Relocate the sensor away from direct airflow or heat. Perform a calibration as described in Section 7. |
| Humidifier/Dehumidifier not activating. | Incorrect settings; appliance not working; appliance lacks auto-restart. | Verify the target humidity and DIFF settings. Ensure the appliance is plugged into the correct outlet and is functional. Confirm your appliance has an auto-restart function. |
| Zobrazení teploty je nesprávné. | Sensor issue or environmental factors. | Ensure the sensor is not exposed to extreme temperatures or direct sunlight. The controller measures, but does not control, temperature. |
