(SW2), to come to the place of the display where the temperature is shown and which is marked
by No.1 on the “CONTROL PANEL”. Then by pressing the button (SW3), you can change the
temperature which is in an interval (30-
75˚C), by step of 5˚C. In order to choose whether we will
heat the water in the heater by heater 1 or heater 2, or by a combination of heater 1 and 2, it is
needed, with the button (SW2), to arrive to the part of the display where the two heaters are
marked. Then, with the button (SW3) we make a choice of a heater. By the same procedure, he
clock is set, as well as the time for postponed heating of the water and its end.

the heater for the water is in a mode for postponed heating of the water, then by pressing the
button (SW4) it will change into a mode for heating the water at the desired temperature which
we have set before. The same can be changed during the heating.

6. MISTAKES:
If the following mistakes appear at the display, the system will stop working.
6.1 If a mistake E1 appears on the display, it means that the sonda (sensor) is interrupted.- Call
the service agency to determine the reason for the mistake.
6.2 If a mistake E2 appears on the display, it means that the water in the system is ≥80 ˚C. –The
maximum temperature is being reached.
6.3 If a mistake E3 appears on the display, it means that there is no water in the water heater.-
Call the service agency to check why the water heater is left without water.
6.4 If a mistake E4 appears on the display, it means that electric power higher than 22mA flows
through the protective conductor.

When the heater shall not be used during a longer time, it must be disconnected from the electric
network. At any risk for freezing of water in the water heater, the water must be emptied from it.
Water is discharged from the heater via the inlet pipe. To this purpose, a special fitting (t-fitting)
shall be mounted between the relief valve and the heater inlet pipe, or a discharge tap. Before
discharge, make sure the heater is disconnected from the power supply, open the hot water on
the connected mixer tap. After discharging through the inlet pipe, there is still some water left in
water heater. The remaining water will be discharged after removing the heating flange, through
the heating flange opening. The external parts of the water heater may be cleaned with a mild
detergent solution. Do not use solvents and abrasives. Regular preventive maintenance inspec-
tion and sure faultless performance and long live of your heater. The lime coating and sediment
on the walls of the tank and on the heating element is a product of quality, quantity and tempera-
ture of the water flowing through the water heater. The maintenance service provider shall also
issue a condition report and recommend the approximate date of the next inspection. Never try
to repair any possible faults of the water heater by yourself, but inform about it the nearest au-
thorised service workshop.
