Heat pump water heater – OPERATING AND MAINTENANCE INSTRUCTIONS
34
The temperatures that can be obtained in the heat pump mode
vary between 50 °C and 55 °C, by factory default
setting. By accessing the installer menu (illustrated in Paragraph 7.7), the interval range can be extended to between
40 °C and 62 °C (bear in mind that temperatures exceeding 55 °C in the heat pump mode may lead to greater wear
of the compressor).
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.
(recommended for winter to ensure the better comfort).
•
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.
•
BOOST 2 (to be activated through the installer menu):
Compared to Boost, the Boost2 mode remains active
even after the set temperature is reached.
•
GREEN
: the water heater will use the heat pump, thereby ensuring maximum energy saving! The maximum
temperature that can be reached depends on the value of the P3 parameter (51 °C-62 °C) – refer to Paragraph
7.7. 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, defrosting process in progress, anti-legionnaire’s disease). This
function is recommended for air temperatures above 0 °C during the hours of heating.
•
PROGRAM
(to be activated through the installer menu)
:
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 elements.
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, in which case it may appear the
symbol of the waves.
•
VOYAGE
(to be activated through the installer menu)
:
studied for situations in which users are absent from
the appliance’s operating location; this mode allows for programming the number of days of absence, during
which the water heater will remain turned off. The appliance will activate only to supply hot water on the day of
arrival; protection against corrosion will continue to be guaranteed while the product will automatically ensure
that the temperature of the water in the tank does not fall below 5 °C. Press the “mode” button until selecting
the VOYAGE mode, turn the knob to set the number of days (“days”) then press the knob to confirm. The
display will only visualize the number of days that remain until the product’s reactivation.
For example, when leaving home on a Saturday morning to return on the Sunday of the successive week, on
Saturday morning it will be necessary to programme 7 nights of absence so as to have hot water available upon
returning home on Sunday. To stop this function press the button “mode”.
