BOOSTER
FUNCTION
When the BOOSTER button 4 is pressed, the
warning light 5 switches on and the upper heating
element switches on. This function will provide
you with a small amount of water (about 20 ÷ 30%
of the total contents) in a very short time.
The temperature is pre-set to the maximum set-
up value of the thermostat. Knob 3 has no effect.
Warning light 1 switches on when the upper heating element is working.
NORMAL
FUNCTION
When the NORMAL button 6 is pressed, the warning light 7 switches on and the upper heating
element is switched on first, followed by the lower element, in order to guarantee total heating.
Knob 3 can be used to adjust the temperature up to a maximum temperature of 75°C. When
the knob is turned to E (Economy), water temperature is preset at about 60°C.
