The heater switches on automatically straight after reaching the flow
rate over 2,5 l/min. The te mpera tu re control system adjusts the
power rate according to the water flow rate, required temperature
and the water temperature in the mains. The LCD red colour back-
light and icon signalises the heating operation. If the unit reach
the maximum power value which is too low for a given operating
conditions the LCD display will show . The LED display backlight
also turns. The heater switches on automatically straight after

the power rate according to the water flow rate, required tempera-
ture and the water temperature in the mains. The LED display back-
light also turns on while pushing or turning the setting knob. The
backlight will automatically turn off when the heating operation is
turned off, or if more than 30 seconds have passed since the last

the unit will stop heating. The unit will
not heat again until the failure is resolved and the appropriate rate
of water flow is reached. If you try to set the temperature above the
