The heater switches on automatically straight after reaching the flow rate over 2,5 l/min. The temperature
control system adjusts the power rate according to the water flow rate, required temperature and the temperature
of water in the mains. The LCD backlight and icon signalises the heating operation. If the unit reach the maxi-
mum power value which is too low for a given operating conditions the LCD display
will show “INSUF POWER’’. The LED display backlight 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 50 se-
conds have passed since the last adjustment.
If you block the unit by master appliance (NA entry) the display will show
“NA BLOCK”
If the fault occurs the display will show icon and error message.
