Turning the controlling button counter-
clockwise, the desired temperature
can be set at higher degrees, see
Figure 5./2.
In case of failure of the controller, the
reducing device saves the hot water
tank against damaging overheating in
the way that before the temperature
of hot water stored reaches 110ºC-t, it
breaks the circuit of the heating.

7.2.2 Temperature controlling and
reducing device (built together)
Adequate operation is ensured by a
temperature
device set at a control temperature of
65 ºC, built in a common house. The
controlling temperature
reduced with the help of a setting
button. The setting button can be
accessed after removal of the cover of

7.3 Compact heater
In case of failure of the compact
heater, its replacement can be
be performed after switching off the
a water tank from the electric system,
after fully emptying the water tank,
through removal of screws of the
closing cover.
Its reparation can only be performed
by a professional technician.
7.4. Active anode
As a supplementary accessory, the
hot water tank is equipped with an
be
active anode to protect it against
corrosion. The life expectancy of
the active anode depends on the
conditions of water and operation.
The state of the anode has to be

The date of repeated check is
defined by the repair technician. If
the diameter of the anode shrinks to
