AQQA 60-120 Gallon Fish Tank Heater

Temperature Range: 59℉-93℉/15℃-34℃ - Each press of the button increases by 1℉/1℃. - The temperature range loops between 59℉ and 93℉, cycling back to the lowest when you reach the highest.

Dry Burning-resistant Protection: - Automatically powers off and displays an error code E0 when the heating rod is out of water by 2.4 inches. - The heating rod automatically repairs itself by submerging back into water. - Ensure you place the device in water before turning it on, and remove it once the heating rod cools down to extend its lifespan.

Electricity Leakage and Overtemperature Protections: - When the heating rod detects water temperature 3℉/3℃ above the set temperature, it flashes the current number to indicate a high temperature alarm and stops heating. - It automatically resumes normal operation once the water temperature drops back to the set temperature.

Fast Heating and Intelligent Controller: - The heating activates when the water temperature is 1℉/1℃ below the set temperature. - The heating stops automatically when the set temperature is reached. - A red light indicates heating, a green light signifies reaching the set temperature, and the light line disappears if an error code is triggered.

Precautions for Use: - Due to prolonged use, scale formation on the heating rod can affect heat dissipation and safety. - Regularly disassemble the heating rod shell to clean it to prevent safety issues.
