When you start up the appliance, all indicators on the control unit will light up for 3
seconds, the buzzer will ring twice, and then the display will show up. If no setting is
entered for 1 minute, all indicators will turn off automatically, except for the Fill Water
indicator, which will flash, and the Outlet Temp indicator, which will illuminate
continuously.
When the tank is filled, please, press the ON\OFF button. Then the Fill Water
indicator stops flashing and the rest of the function become available for setting. After
completion of all settings, please, press the ON\OFF button again. Then the Fill Water
indicator goes off, and the appliance starts to operate.
When the appliance runs and no operating instruction has been received or
malfunction has occurred for 30 seconds, the backlight of the display goes out
automatically, except the Operating Mode, Outlet Temp and Lock indicators. If there is
no operation for half a minute, the display will lock automatically, but the Lock indicator
will illuminate independently.

Setting the energy sources allowed
With the basic settings, the appliance also operates as a heat pump
utilising the thermal energy of the external environment.
If the ambient temperature decreases below the operating parameters, the
heat pump can no longer generate the heat needed for the production of
domestic hot water, therefore the heat pump stops, automatically switches
to the use of the auxiliary electrical heating and enables the E-heater mode.
The display shows the text 'LA' then. When the external temperature
conditions allow the use of the heat pump again, the electrical heating
stops and the heat pump unit restarts, causing the text 'LA' disappear from
the display.
When the setting water temperature is higher than the temperature that
the heat pump can produce in itself at the given ambient temperature, the
heat pump runs first until the possible water temperature is reached, and
then, the E-heater is activated automatically, while the heat pump stops;
in the meantime, the appliance ensures the continuous heating of water.
If electrical heating is activated manually while the heat pump is running,
the heat pump and the electrical heating will run in parallel, until the setting
temperature is achieved. Therefore, if you need hot water very quickly, you
can use the two modes operated in parallel.
If you press the E-heater function button once, the electrical heating will
be activated for a single heating cycle only. If you want the electrical
heating to run over several heating cycles, press the E-heater button once
again.
