Heat pump water heater – OPERATING AND MAINTENANCE INSTRUCTIONS

7.3 Setting the temperature

The desired temperature for the hot water can be set by turning the knob clockwise or anti-clockwise (the visualized
temperature will flash temporarily).
To visualize 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 45 °C and 55 °C.
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
appear:
•
AUTO: 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 P9 – TIME_W parameter (see Paragraph 7.7), which is set to 8 hours by default.
•
BOOST: 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: 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 turn on only in the event that occurs
inhibition of operation of the heat pump (errors, air temperature out of operating range, anti-legionnaire's
disease)..
•
PROGRAM: 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, 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. 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.

7.5 Time setting

You can set the current time the first time you turn ON the product.
Turn the knob until you find the current hour and confirm by pressing the knob.
Repeat the procedure to set the minutes.
You can also set the current time through the parameter P1 (paragraph 7.7).
The device does not update automatically, reset the time in the passages from
daylight saving time to standard time.
