The water temperature from the water heater to
the taps is adjusted with knob A.
Important: Start by turning knob A fully counbter-
clockwise (towards +). Then turn A as described
in the diagram (right) to select the preferred
water temperature.
Adjusting the valve does not affect the water
temperature in the water heater, which is
factory set at 75°C to avoid bacterial growth /
legionella.
