Rapid heating speed
Fastest 5 seconds warming for 60-180 gallon fish tank. The internal material is updated and upgraded with titanium steel material, which is safer to use, not easy to deform, and has very strong corrosion resistance. It will automatically reduce power when approaching the set temperature, fully utilizes thermal energy inertia to smoothly reach the set temperature.
Over-temperature protection prevents water from over heating. When the water temp exceeds about 93.5 °F, it starts alternately flashing ‘EE’ fault code; if it is over 97°F, the water heater will stop heating automatically. When the water temperature cool down to 93°F, the aquarium heater will start working automatically. In addition, it has a power-off memory function. No need to set it again.
When the heating rod is exposed to air, it will display ‘ER’ fault code, and the heater will shut off automatically. When the heating rod is completely immersed, it will start working automatically.
Directions for Use
1. When using this heating equipment, the heater should be submersed in water and should not be exposed to the water surface.
