• P11 PARAMETER - PHOTOVOLTAIC MODE "
If you have a photovoltaic system, you can set the product to op-
timise use of the electricity produced. After having done the elec-
trical connections as described in paragraph 4.11 fig. 14 and set the
P11 parameter to other than "0".
The signal should be received at least for 5 minutes to enable the
photovoltaic function (once the product starts a cycle, it will oper-
ate for at least 30 minutes).
When the signal is detected, the operating mode works as follow::
- OFF (value 0 – default)
PV mode disabled
- PV_HP (value 1)
When the signal from the inverter is present. The product will
reach the set temperature (the highest between T SET POINT
and PV TSET) with only the heat pump (max 62°C).
- PV HE (value 2)
The product will reach the set temperature (the highest between
T SET POINT and PV TSET) operating with only the heat pump
up to 62°C and if needed with the heating element (1500 W).
- PV_HEHP (value 3)
set temperature (the highest between T SET POINT and T W PV)
is achieved with the heat pump and the heating element (1000
W) up to 62°C. For higher Temeratures than 62 °C the second
heating element (1500 W) is activated.
• P13 PARAMETER - SG FUNCTION
If you have an SG signal, you can connect the signal cable as de-
scribed in the "electrical connections" chapter when the function
P13 is enabled the SG icon will be displayed.
Once the SIG2 signal has been received for at least 5 minutes
(once the product starts a cycle, it will work for at least 30 minutes),
the name of the selected mode alternates with the text SG ON and
the current operating mode is automatically changed by thermo-
stating the product at set temperature (the maximum between T
SET POINT and PV TSET), operating only with the heat pump (max
62 ° C).
• P16 PARAMETER - SILENT
This function reduces the sound level (performance can vary from
those declared). It can be enabled via the P16 parameter on the in-
staller's menu. Once activated, the symbol appears on the display
"
".
ANTI-FROST FUNCTION
If the temperature of the water in the tank falls below 5 °C while the
appliance is powered, the heating element (1000 W) will be automat-
ically activated to heat the water up to 16 °C.
DEFROST "
"
The defrost function is activated when the heat pump has been work-
ing for at least 20 minutes, the detected air temperature is below
15°C and the evaporator temperature is decreasing rapidly. When the
defrost cycle is running, the icon to the side is displayed.
