temperature reaches the set point, the heating
element is automatically switched off.
Levels of water heater protection:
• protection against overheating;
• protection against excessive hydraulic
pressure.
• RCD (Ground Fault Interrupter).
The steel inner tanks with a special protec-
tive coating are made using the advanced
electrostatic dry enameling method. Enamel
properties:
• increased adhesive ability and high ductility
(hardened at 850 °C);
• expands or contracts with temperature
changes in the same proportion as the
walls of the inner tank, without creating
micro-cracks that could lead to corrosion.
As additional protection against corrosion of
the internal tank, the water heater is equipped
with a magnesium anode. The dry heating
element (PHE) is placed in protective metal
covers, which exclude direct contact of the
heating elements with water, respectively, no
scaling is formed on the heating elements,
which increases their service life and prolongs
their service life.

mode, the water in the device is heated to
a temperature of 70 ° C and held at this
level for 20 minutes. The mode allows you
to stop the reproduction of bacteria, for
example legionella, multiplying in water
when the device is not used for a long
time.
3. Button " C" In order for the heating mode
o
and temperature to be displayed on the
screen, it is necessary to briefly press but-
ton 3 once or change the power mode or
target temperature.
4. Temperature knob
off — the mark corresponds to the mini-
mum water temperature in the water heater
(heating off), there is a characteristic click.
low — the mark corresponds to the
minimum water heating temperature in the
water heater (heating on).
eco — the eco-mode mark corresponds to
the water heating temperature in the water
heater about 50-55 °С.
high — the mark on the right corresponds
to the maximum heating water temperature
in the water heater (75 °С).
Regardless of the selected power mode, you
can use the adjustment knob to select the
temperature to which you want to heat the
water.
Setting the current time:
It is set automatically when connected to the
application. If there is a connection, there is a
regular check and, if necessary, time adjust-
ment. Optionally, the water heater has an inde-
pendent clock and a backup battery, which
allows you to restore work on schedule in case
of power failures up to 72 hours. In order to
view the current time, you need to briefly press
the button 3 once. If the time is set, the current
time will be displayed on the screen. If the time
is not set, then a running line will be displayed
on the display «not set – connect to APP»
Setting the "Antifreeze" mode
This mode is always active when there is
power, regardless of the position of the poten-
tiometer. When the No Frost mode is activated,
the display shows the inscription nF. Logic of
operation: if the current temperature of the
water in the tank drops to +4 ° C, power mode
II is activated, and the water will be heated to
+7 °C. When the water in the tank reaches +7
°C, the heating elements will be turned off.
