e heater switches on automatically straight aer reaching the ow rate over 2,5 l/min. e temperature
control system adjusts the power rate according to the water ow rate, required temperature and the temperature
of water in the mains. e 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’’. e LED display backlight also turns on while pushing or turning the setting
knob. e backlight will automatically turn o when the heating operation is turned o, 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.
• ER>T INLET – inlet sensor failure,
• ER> T OUTLET – outlet sensor failure,
• ER> T MAX – temperature has exceeded the maximum value,
• ER> AIR 1 – air bubbles in the heating box – equipment detection,
• ER> AIR 2 – air bubbles in the heating box – program detection.
If the display shows ER> T MAX, ER> AIR 1 or ER> AIR 2 the unit will stop heating.
e unit will not heat again until the failure is resolved and the appropriate value of water ow is reached.
8.1. Temperature adjustment.
Turn the knob to the right to increase the temperature value, or to the le to decrease it.
Push the knob to read the temperature value that is stored in memory. Push it again to read the next stored value.
You can switch between the following settings “SINK”, “SHOWER” and “BATH”.
To change the temperature setting in memory:
• select the temperature setting by pushing the control knob,
• push the knob and keep for about 3 seconds until the value starts to ashing,
• turn the knob to adjust the value,
• push the knob to save the value.
Notice: save the new value within 10 seconds, otherwise you will lose it.

8.2. Conguration and parameters view.
Push and keep knob for about 5 seconds until the display shows „S>SET TEMP". Some of paramaters are
only for view mode (e.g. T INLET or FULL POW) but some parameters user can change (e.g. brightness or langu-
age).
Turn the knob to switch between a parameters.
• temperature (min-max) [ S>SET TEMP] – 0C,
• inlet temperature value [S>T INLET] – 0C,
• outlet temperature value [S>T OUTLET] – 0C,
• ow rate [S> FLOW] – l/min,
• percentage of maximum power with which the unit currently heats [S> FULL POW] -%,
• work time [S> T – h],
• minimum brightness / stand-by-mode [S> BRIGH MIN] [0 - BRIGH MAX],
• maximum brightness / active [S> BRIGH MAX] [BRIGH MIN -25],
• select language version [S> ENGLISH] (POLSKI, FRANCAIS, ENGLISH, DEUTCH, РУССКИИ),
• soware version (PW ........, MSP........).
Push and keep knob for about 5 seconds (until the display backlight turns o) to exit parameters setting mode.
Notice: parameters setting mode will automatically exit aer 5 minutes since the last adjustment.
8.3. Maximum temperature..
Set the maximum temperature value then push and keep knob for about 5 seconds until the display shows
. Take notice that the new maximum temperature value will be saved in memory for other settings as well.
To cancel the maximum temperature value, push and hold the knob for about 5 seconds (until the display shows
while you set the temperature above the minimum value.
If you try to set the temperature above the adjusted maximum value the display will show for about 1 se-
cond..
