Product Features 1. Energy-saving: PID tech adjusts frequency & power as needed. Quick heat-up or maintain temp to save energy & costs. 2. Based on Renesas chip, auto shut-off on low water, resumes on submersion. Three overload sensors prevent burnout. Beeps if water temp >96.8°F. Keeps fish safe & temp stable. 3. At-a-glance Display: Shows real-time temp & power. Red=full power heating, green=low power, no light=proper temp reached. 4. Easy Set Dial: External button control, cycle through temps easily. Adjustable 70°F-94°F in 1°F increments. No need to get your hands wet. 5. Unbreakable & Fast Heating: Heavy-duty, explosion-proof metal. Fast heating for ponds. Plastic guard protects fish/turtles. Auto Shut Off: The hygger 011 aquarium heater features an automatic shut-off function that activates with a beeping alarm and error code when the water level is too low or not fully submerged, ensuring safety. It resumes operation once the heater is fully submerged. The heater is equipped with three overload sensors to prevent burnout. Additionally, it has a beeping alert system that triggers if the water temperature exceeds 96.8°F. Energy-saving PID Variable Frequency Drive Technology: The smart heater incorporates advanced PID Variable Frequency Drive Technology, which optimizes energy consumption. When the water temperature is within a 0.5°F to 1°F range below the set temperature, the heater intelligently switches to a low-power frequency mode, conserving energy and reducing electrical costs. This feature ensures efficient low-power startup and contributes to energy savings. Thanks to the smart PID control system, the heater dynamically adjusts its frequency based on real-time needs, making it an outstanding energy-saving device. Digital Display Water Real-time Temperature: The smart aquarium heater provides a clear, simultaneous view of the real-time water temperature and power status on the heating rod’s LCD. The indicator light glows red during heating and turns off when the desired temperature is achieved. Explosion-proof: The hygger 011 aquarium heater is designed with robust, explosion-proof materials and features a double-layered plastic guard to ensure safety. This protective barrier prevents fish from making contact with the heating element. Ideal for use in freshwater aquariums, an 800-watt model is recommended for aquariums up to 180 gallons in capacity. Overheating Protection: The heater is equipped with three temperature probe sensors to prevent overheating effectively. Combined with a premium, high-temperature-resistant plastic guard, it safeguards fish and other aquatic life from coming into contact with the heating element. Secure Firmly: Secure the smart heater with a triple suction cup bracket to keep it firmly in place within your fish tank. Easy to Set The Water Temp: Easily adjust the water temperature with the built-in external temperature control, keeping your hands dry throughout the process. Simply press the button to cycle through the temperature range from 70°F to 94°F (20°C to 34°C). The heater also features a combined cord length of 4.9 feet (1.5 meters) and 3.9 feet (1.2 meters) for added convenience. Easy to Clean: The heater is equipped with a detachable plastic guard, making it easy to clean the heating rod regularly to prevent clogging from water scale buildup.
