താപനില നിയന്ത്രണം

• Water Flow Knob: Adjusts the water flow rate. Higher flow rates may result in slightly lower outlet temperatures, while lower flow rates allow for higher temperatures.
• Gas Flow Knob: Controls the gas supply to the burner, directly impacting the heating power and water temperature. Turn towards 'Max' for hotter water and 'Min' for cooler water.
• Summer/Winter Switch: This switch allows for seasonal adjustment of heating power.
  • സമ്മർ മോഡ്: Reduces gas consumption, suitable for warmer months when incoming water temperature is higher.
  • വിന്റർ മോഡ്: Increases gas consumption for colder months when incoming water temperature is lower, requiring more heat to reach desired output temperature.

കുറിപ്പ്: Sufficient water flow (minimum activation rate: 0.66 GPM) is required for the unit to activate and prevent the overheat safety sensor from shutting off the unit.
