Due to a special knob on the control panel, you are able to use multiple cleaning cycles in a row, which increases the
probability of complete elimination of bacteria.
ECO function is activated by pressing the” ECO” knob on the control panel. To deactivate the function, press the same knob
again.
Warning:
During the operation the function you cannot control the heating temperature, as it is selected automatically
according to the inherent logic of the ECO mode. But if ECO function is enabled for more than two consecutive weeks, the
water heater automatically enters economy mode, in which it will heat water based on your average needs.
Anti-bacteria function
The water heater has also a fully-automated anti-bacteria mode.
Control over anti-bacteria cycles of this function is implemented using the water heater program, and it is disabled by
default. Automatic mode is activated under certain conditions when you do not use the ”ECO” knob on the control panel.
Namely this mode provides extra protection against malignant bacteria containing in the warm water.
The fi rst cycle begins three days after the product is switched on. Subsequent cycles are performed every 30 days if, during
that period, the water is not heated to 70°C at least once. When the water heater is switched off , the anti-bacteria function
is disabled. If the appliance is switched off during the anti-bacteria cycle, the product shuts down and the function is
disabled. At the end of every cycle, the operating temperature reverts to the value set previously by the user.
The activation of the ECO anti-bacteria cycle is displayed as a normal 70°C temperature setting. To
disable the anti-bacteria function on a permanent basis, press and hold the «ECO» and «+» buttons
simultaneously for four seconds; the LED 40°C will fl ash rapidly for four seconds to confi rm its deactivation. To reactivate
the anti-bacteria function, repeat the procedure described above; the LED 50°C will fl ash rapidly for four seconds to
confi rm its reactivation.
During the ECO automatic anti-bacteria cycle, the display alternates between the temperature of the
water and the text “-Ab-”. To disable/enable the function, while the water heater is in operation, press
and hold the “Mode” button for fi ve seconds. Select “Ab0” (to disable the function) or “Ab1” (to enable
the function) by turning the “Set” (Setting) knob, and then confi rm it by pressing the knob. After the function has been
disabled/enabled, the indication on the water heater control panel will revert to its normal operating status.
