When the tank is filled, please, press the ON\OFF button. Then the Fill Water indicator
stops flashing and the rest of the functions become available for setting. After
completing 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.
In ECO, AUTO, PROGRAM and BOOST modes, the water temperature can be selected
using the
and
The constantly showing temperature indicates the actual water temperature in the
tank.
The flashing temperature with an arrow indicates the desired water temperature.
With the basic settings, the appliance operates as a heat pump – in ECO mode –
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 sanitary hot
water, therefore the heat pump stops, and automatically switches to the use of the
auxiliary electrical heating enabling the auxiliary electrical heating mode. When the
external temperature conditions allow the use of the heat pump again, the electrical
heating stops and the heat pump unit restarts.
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 auxiliary electrical
heating is activated automatically, while the heat pump stops; in the meantime, the
appliance ensures the continuous heating of water.
