7.7 Installer menu
CAUTION: THE FOLLOWING PARAMETERS MUST BE ADJUSTED BY QUALIFIED PERSONNEL.
Several of the appliance’s settings can be modified through the installer menu. The
maintenance symbol is 51isualize51 on the left.
To enter the menu, keep the knob pressed for 5 seconds then scroll the parameters
of the “L – INFO” menu until reaching “PO – CODE”.
After entering the code (illustrated in the table that follows), turn the knob to select the
parameters P1, P2, P3 … C2.
Upon reaching the parameter to be modified, press the knob to 51isualize the parameter’s
value then turn the knob to set the desired value.
To return to the parameter selection area, press the knob to store the entered parameter or
press “mode” (or wait 10 seconds) to exit without storing the entered value.
To exit the installer menu, press the “mode” button (the appliance will ensure that
the menu is automatically exited after the latter has been idle for 10 minutes).
Parameter
Name Parameter description
P0 CODE
Code entering to access the installer menu. The number 222 appears on the display: turn
the knob until reaching number 234 then press the knob. It will then be possible to access
the installer menu.
P1 T Max
Adjustment of the maximum obtainable temperature (from 65 °C to 75 °C).
A higher temperature value allows for using a greater amount of hot water.
P2 T Min
Adjustment of the minimum obtainable temperature (from 50 °C to 40 °C).
A lower temperature setting allows for more energy-efficient operation in the event of
limited hot water consumption.
P3 T HP
Adjustment of the maximum temperature obtainable with the heat pump unit (from 50 °C to
62 °C). Bear in mind that operating at temperatures above 55 °C with the heat pump may
lead to greater wear of the compressor.
P5 ANTI_B
Activation/deactivation of the anti-legionnaire’s disease function (on/off).
See Paragraph 7.9.
P6
VOYAG
E
Activation/deactivation of the Voyage function (on/off).
See Paragraph 7.4.
P7
DEFRO
S
Activation/deactivation of the defrost mode (on/off).
If activated, this mode allows the heat pump to function at air temperatures as low as -7 °C.
P8 HC-HP
Activation/deactivation of the two-tier rate operation mode with HC HP signal (Warning:
activate it only if signal cable HC-HP is connected). See Paragraph 7.11.
P9 TIME_W Maximum number of hours of daily heating (from 5h to 24h).
P10 RESET Resetting of all factory default settings.
P11 PROG Activation/deactivation of the Program function: P1, P2, P1+P2 (on/off).
P12 BOOST2 Activation/deactivation of the Boost2 function (on/off).
P15 AUTO
Activation/deactivation of the Auto function (on/off).
See Paragraph 7.4.
P16 HYST
Adjustment of compressor Hysteresis (3-12 ° C). Hysteresis is the temperature difference
of the thermostat. This parameter allows the user to change the compressor response: the
lower the hysteresis, the faster the compressor response.
C1 CHECK
Activation of the electric connection check (activate this only in presence of mains
alimentation and air temperature below 30 °C).
