WARNING
To guarantee safety and correct operation of the system
interface, it must be commissioned by a qualifi ed techni-
cian in possession of the skills as required by law.
IGNITION PROCEDURE

17.0 User parameters
17.0.0 CH mode
- Green
(excludes the electric resistances for the integration of
the heating)
- Standard
Press the OK button to confi rm.
17.0.1 Quiet Mode Activation
Press the OK button to confi rm.
"and "OK" buttons un-
Turn the knob and select:
- ON (active function to reduce noise)
- OFF
Press the OK button to confi rm. Turn the knob and select:
17.0.4 Domestic Hot Water BOOST
Press the OK button to confi rm.
Turn the knob and select:
- ON (enable the boost cycle to speed up the DHW servi-
ce. Max duration 180 min.)
- OFF
17.0.5 Delta T PV sanitary setpoint
Turn the knob to set the value that encreases the
sanitary setpoint when the PV contact is supplied.
17.1 EM INPUT OUTPUT CONFIGURATION
Press the OK button to confi rm. Turn the knob and select:
17.1.0 HV Input 1
- Not defi ned: no function associated to the input. Fault
941 is displayed.
- Absent: Input not enabled.
- EDF (night tariff ): Input not active (0V). If the Comfort
function (par .17.5.2) is set as HC-HP the heat pump and
the heating resistors tank charge is suspended; if the
comfort function is set as HC-HP 40°C, the tank charge
is limited, considering as DHW setpoint temperature the
minimum between the reduced setpoint temperature
and 40°C. Inut active (230V). The heat pump and the
resistors are enabled for the tank charge following the
standard logics.
- SG Ready 1: input signal nr 1 for the SG Ready standard
(see. Paragraph SMART GRID READY STANDARD)
- External Switch OFF signal: input signal to set the the
machine OFF. Every heat request, cooling request and
DHW service is stopped and antifreeze protection lo-
gics are active.
17.1.1 HV Input 2
- 0. Not defi ned: no function associated to the input. Fault
942 is displayed.
- 1. Absent: Input not enabled.
- 2. DLSG (load shedding): Input not active (0V). Heating
resistors are disabled in every cycles.
- 3. SG Ready 2: input signal nr 2 for the SG Ready stan-
dard (see. Paragraph SMART GRID READY STANDARD)
17.1.2 HV Input 3
- 0. Not active
- 1. PV integration active: Input not active (0V), no tank
integration from PV system. Input active (230V): if the
system is in stand-by, the DHW setpoint temperature is
incremented by the amount defi ned by the parameter
17.0.5 - PV Delta T DHW setpoint temp.
17.1.3 AUX Input 1
- 0. None
- 1. Humidistat: when the contact is closed, the heat pump
switches off
17.1.4 AUX Output 1 (AFR)
- 0. None
- 1. Fault alarm: the contact is closed in case of fault
- 2. Humidistat alarm: the output is closed when the AUX
1 is set as humidistat and it is closed.
- 3. External heat request: the contact is closed to gene-
rate an heat request to a external heat source instead of
the heating resistors.
- 4: Cooling Request: the contact is closed to generate a
cooling request to an external cooling source
17.1.5 AUX Output 2 (Come AUX1 OUT1)
