• Water Flow Knob: Adjusts the rate of water flow through the heater. Higher flow rates may result in slightly lower temperatures, while lower flow rates allow for hotter water.
• Gas Intensity Knob: Controls the gas supply to the burner, directly affecting the heating power and water temperature. Turn clockwise for higher temperature, counter-clockwise for lower.
• Seasonal Adjustment Knob: Optimizes gas consumption based on the season. Use the 'summer' setting for reduced gas usage when ambient water temperature is higher, and the 'winter' setting for maximum heating.

6.3 Digital Display

The digital display shows the real-time hot water outlet temperature. This allows for precise temperature monitoring and adjustment.
