Heat pump water heater - OPERATING AND MAINTENANCE INSTRUCTIONS FOR THE USER

7.2 Turning the water heater on/off

Turning the appliance on: simply press the ON/OFF button to turn the water
heater on.
Now you can set the current time (see section 7.5)
The DISPLAY visualises the "set" temperature and operation mode, while the HP
symbol and/or heating element symbol indicate the operation of the heat pump
and/or heating element respectively.
Turning the appliance off: simply press the ON/OFF button to turn the water heater off, only "OFF" appears on the
display. The protection against corrosion is still ensured, while the product will automatically ensure that the temperature
of the water in the tank does not fall below 5°C.

7.3 Setting the temperature

The desired temperature for the hot water can be set by turning the knob clockwise or anti-clockwise (the visualised
temperature will flash temporarily).
To visualise the current temperature of the water in the tank, press and release the knob; the relative value will appear
for 8 seconds then the set temperature will reappear once again.
The temperatures that can be obtained in the heat pump mode vary between 50°C and 55°C, by factory default
setting, and 40°C-55°C, by varying the setting on the installer menu.
The maximum temperature that can be obtained with the heating element is 65°C, by factory default setting, and
75°C, by varying the setting on the installer menu.

7.4 Mode of operation

In normal operating conditions, the "mode" button can be used to vary the
operating mode through which the water heater reaches the set temperature. The
selected mode will be visualised on the line below the temperature.
If the heat pump is active, the following symbol will appear:
If the heating element is active, the following symbol will

AUTO: mode: the water heater understands how to reach the desired temperature in a few hours, through the
rational use of the heat pump and, only if necessary, of the heating element. The maximum number of hours it
takes depends on the P4 – TIME_W parameter (see Paragraph 7.7), which is set to 8 hours by default.
(recommended for winter).

BOOST: mode: by activating this mode, the water heater simultaneously uses the heat pump and heating
element to reach the desired temperature in the shortest possible time. Once this temperature is reached, the
AUTO operating mode is restored.

GREEN: mode: the water heater will use the heat pump, thereby ensuring maximum energy saving! The
maximum temperature that can be reached is 55°C. The heating element may also turn in case of errors or anti-
legionnaire's disease. This function is recommended for air temperatures above 0°C during the hours of heating.

PROGRAM mode: You have two programs P1 and P2, which may act either individually or in combination with
each other during the day (P1 + P2). The device will be able to activate the heating phase to reach the selected
temperature set in the timetable, giving priority to heating by heat pump and, if necessary, through the heating
element.
Press the mode button to select the desired Program mode (P1/P2/P1+P2), turn the knob to set the desired
temperature, press it again to confirm, turn the knob to set the desired time and press to confirm; mode P1 + P2
can set the information for both programs.
In the case of electrical connection with two-tier price signal HC / HP, you still possible program the water heater
at any time of day.
For this function is required the setting of the current time, see the next paragraph.
Note: To ensure comfort, in the case of P1 + P2 mode operation with very close times between them, it is
possible that the temperature of water is higher than the temperature set.
Note: with small tappings the compressor does not restart immediately, even if the temperature is lower than the
set-point temperature.
