Hygger Digital Heater

Product Overview:

• • Dual LED Display: Real-time monitoring of both the current water temperature and your desired set temperature.
  • Explosion-Proof Construction: Built with heavy-duty quartz glass or titanium and encased in a protective ABS guard to prevent fish from getting burnt.
  • Dry-Run Protection: Automatically cuts power if the water level drops below the sensor, displaying an error code (typically “Er” or “E1”).
  • Memory Function: Retains your temperature settings following a power cut.

1. 1. Placement: Secure the heating rod to the glass using the provided suction cups. It must be placed in an area with high water flow (near a filter outlet or wave maker) to ensure even heat distribution.
   2. Submersion: Critical: The heater must be fully submerged before being switched on. Never bury the unit in sand or gravel.
   3. Setting the Temperature:
      • • Plug the unit into the mains.
        • Press the ‘SET’ button on the external controller until the digits flash.
        • Cycle through to your preferred temperature. The display will blink three times to confirm and save the setting.

   4. Indicators: A red light typically indicates active heating, while a blue or green light shows the aquarium has reached the target temperature and the unit is in standby.

• Drip Loop: Always form a “drip loop” in the power cable to prevent water from running down the wire into the electrical socket.
• Water Changes: Always unplug the heater and wait at least 15 minutes before removing it from the water or performing a water change to allow the element to cool.
• Cleaning: Periodically wipe the heater guard with a soft cloth to remove algae or calcium deposits, which can interfere with the thermal sensors.
