2. Vigtige sikkerhedsinstruktioner
- Always ensure the heater rod is helt nedsænket in water before plugging it into a power outlet. Operating the heater out of water can cause damage and pose a safety risk.
- After unplugging the heater, allow it to cool down in the water for 15-30 minutter before attempting to remove it from the aquarium. This prevents residual heat from causing damage or burns.
- Sørg for, at der er good water circulation around the heater to allow for even heat distribution and accurate temperature readings.
- Do not operate the heater if the power cord, controller, or heater rod shows any signs of damage.
- Dette produkt er beregnet til kun indendørs brug and specifically for aquariums. Do not use it for any other purpose.
- Unplug the heater from the power outlet before performing any maintenance, water changes, or handling the aquarium contents.
- Keep the external controller dry and away from water splashes.

5. Opsætningsvejledning
- Placering af varmelegeme: Securely attach the heater rod to the inside wall of your aquarium using the provided suction cups. Ensure the heater is positioned horizontally or vertically in an area with good water flow. The heater must be completely submerged in water.
- Controller Mounting: Attach the external digital temperature controller to the outside of your aquarium using its bracket. Position it in a location that is easily accessible for viewing and adjustments, and where it will remain dry.
- Strømtilslutning: Once the heater rod is fully submerged and the controller is mounted, plug the power cord into a standard AC 110-120V/60Hz electrical outlet.

6.2. Indstilling af temperaturen
- To unlock the controller and enter temperature setting mode, long press the child lock button (key icon) for 1-3 seconds. The current temperature display will begin flashing, indicating it is ready for adjustment.
- Tryk på temperature cycle button (up/down arrows icon) repeatedly to adjust the desired temperature. Each press will change the temperature by 0.5°F or 0.5°C. The available setting range is 59°F-94°F (15°C-34°C).
- After you stop operating the controller for approximately 3 seconds, the device will automatically enter the child lock state, preventing accidental changes to the set temperature.
6.3. Skift af temperaturenheder (°F/°C)
Tryk på F/C knap on the controller to toggle between Fahrenheit (°F) and Celsius (°C) temperature displays.
6.4. Intelligent Heating Operation
The AQQA heater features an intelligent constant temperature system:
- When the water temperature is lower than the set temperature, the heater will automatically activate and warm the water.
- Once the water temperature reaches the set temperature, the heater will switch to a low-power mode to maintain the temperature within a 0.5°F/°C difference from the set point, optimizing energy efficiency.
