6. 操作手順

Your Bosch Eco 6 water heater is designed for simple and efficient operation.

6.1 Automatic Ignition

The water heater will automatically ignite when you open a hot water tap, and turn off when the tap is closed. The digital display will show the current water temperature.

6.2 温度と流量制御

The unit features two control knobs on the front panel:

• 温度ノブ： Adjusts the gas flow to control the water temperature. Turning it towards 'Alta' (High) increases temperature, while 'Baja' (Low) decreases it.
• 水流ノブ: Adjusts the water flow rate. Turning it towards 'Alto' (High) increases flow, while 'Bajo' (Low) decreases it.

6.3 Optimal Settings for Temperature Control

The outlet hot water temperature depends on the relationship between the gas flow (temperature knob) and water flow (water flow knob). A higher water flow distributes heat better, allowing the unit to reach a wider temperature range.

• 快適温度： A comfortable water temperature is typically between 40°C and 55°C (104°F - 131°F), depending on personal preference.
• 冬モード: For colder incoming water, set the water flow to minimum and temperature to maximum. This restricts water passage, allowing it to absorb more heat from the flame.
• サマーモード: For warmer incoming water, set the water flow to maximum and temperature to minimum. This allows water to pass at maximum capacity, as the ambient temperature is sufficient for a comfortable range.

7. メンテナンス

定期的なメンテナンスにより、給湯器の寿命と効率が確保されます。

• クリーニング： 定期的にユニットの外側を柔らかくて乾いた布で拭いてください。amp 布。 研磨剤入りクリーナーは避けてください。
