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.
