????LED DIGITAL DISPLAY CONTROLLER: ? Displays real-time water temperature or set temperature, three-digit display, water temperature display accurate to 0.1 °F, easy to read. ? 4 kinds of work instructions - Working/Malfunction/ Thermostatic/ Out of water, easy to understand. ? Child Lock"KEY": need to touch 3 seconds to set the temperature.
????RAPID HEATING: Fastest 5 seconds warming, with intelligent circuit board, work with new PTC ceramic thermal conductive material, the outside is wrapped with aluminum material to accelerate heat conduction and protection. Automatically reduces power when approaching the set temperature, fully utilizes thermal energy inertia to smoothly reach the set temperature, saving energy.
????INTELLIGENT THERMOSTAT: Over-temperature protection prevents "cooking fish". When the water temp exceeds about 93.5 °F, start alternately flashing EE fault code; and over 97?, the heater will stop heating automatically. When the water temp cool down to 93?, the heater will start working automatically. In addition, it has a power-off memory function and no need to set it again.
????ANTI-DRY PROTECTION: When the heating rod is exposed to air, display ER fault code and the heater will shut off automatically. When the heating rod is completely immersed in water, it will start working automatically. Effectively extend the service life. (PS: Suitable for freshwater only.)
????HIGH-QUALITY MATERIALS: Built-in dual temperature probe, real-time monitoring of water temperature, temperature accuracy of ± 1 °F; high temperature resistant ABS material, no deformation and no softening, explosion-proof and anti-corrosion, no leakage of electricity. Strong suction cup bracket, can stably fix the heater in every corner of the fish tank.
