Aquarium Heater (300W for 40-75 Gallon) with Over-Temperature & Dry Burning Protection

Information about AQQA Smart Aquarium HeaterThis aquarium heater provides precise temperature control and robust safety features, ensuring a stable and secure environment for your aquatic pets.Adjustable Temperature with Easy ConversionYou can easily set the temperature within a range of 59℉-93℉ (15℃-34℃). Each press of the button increases the temperature by 1℉/1℃, and the settings conveniently loop from the highest back to the lowest. To switch between Fahrenheit and Celsius, simply press and hold the button for 5 seconds.Dry Burning-Resistant ProtectionSafety is key. If the heating rod is more than 2.4 inches out of the water, it automatically powers off and displays an “E0” error code. It will automatically resume operation once fully re-immersed. To extend its lifespan, always ensure the heater is in the water before powering it on, and let it cool in the water before removing it.Leakage Protection and Overtemperature AlarmThis heater includes an electricity leakage protector and overtemperature protection. If the heating rod detects the water temperature is 3℉/3℃ higher than your set temperature, the current water temperature display will flash as a high-temperature alarm, and heating will stop. It automatically returns to normal once the water temperature drops to your set point.Fast Heating with Intelligent ControlBenefit from fast heating and an intelligent controller. The heater begins warming when the water temperature is 1℉/1℃ below your set temperature and stops once the set temperature is reached. A red light indicates heating, a green light means the set temperature has been achieved, and the light disappears when an error code occurs.Important Usage Precautions:Over time, scale can build up on the heating rod, affecting heat dissipation and potentially leading to safety issues. Therefore, we recommend regularly disassembling the heating rod shell to clean the rod body.
