Continuous Monitoring: The included sensor probe stays inside the water tank to measure and display the real-time water temperature on the LCD screen.
Auxiliary Backup Heating: When there isn't enough sunlight (e.g., at night or on rainy days), the controller triggers the tank's built-in electric heating element (up to 2000W) to reach your target temperature.
Smart Memory: It features a power-off memory function, meaning it retains all of your clock and heating schedules even during a power outage
