NOTA:
* : for the correct reading of this parameter, the va-
lue resulting from the 3 screens must be divided by 10.
Ex. 02859 / 10 = 285,9
** : for the correct reading of this parameter, the value re-
sulting from the 3 screens must be multiplied by 10.
Ex: 02859 x 10 = 28590

2.8.8 HI menu - ELECTRIC HEATER SETTING
Value Description
Enabling heater in ECO mode when
H01 protection alarm
(0=disabled, 1=enabled)
Electric heater ignition upper probe
H02 hysteresis (only for Electric and Booster
modes)
Operating time in AUTO mode for
H03 temperature rise control for switching
on the electric heater
Minimum increase in water temperature
H04 so as not to turn on the heating element
in AUTO mode
Level: U=user menu - I=installer menu
Parameters:
H01: from this parameter it is possible to enable or disable the
switching on of the heater when the unit is working in ECO
mode and the compressor cannot switch on due to an inter-
vention of one of its protections (for example intervention of the
HP pressure switch or air temperature at outside the operating
limits):
H02: Difference between the set point and the heater switch-
on temperature
H03 – H04: These parameters are used when the unit is wor-
king in AUTO mode and you want the heater to be turned on
when the water temperature does not rise by a minimum in-
crease (H04) after a given pump operating time of heat (H03).
NOTE: once turned on, the heater will turn off only when the
water temperature reaches the set point
2.8.9 Phv menu - EVU functionality - Photovoltaic functio-
nality
If parameter G01=1 is set (smartgrid enabled), the
EVU and photovoltaic functions are not available. To
enable them, set parameter G01=0 (smartgrid not ena-
bled).
2.8.9.1 EVU functionality (see also "6.8.1 Remote connec-
tions")
This function is indispensable if a subsidized electricity tariff is
subscribed for heat pumps. The aim is to facilitate operation
when the cost of electricity is low, but still having to comply with
the rules of the energy supplier who will be able to decide when
to interrupt the supply.
To meet this requirement, the water heater electronics are fit-
ted with a digital input which, when opened, allows the unit to
be switched off and thus reduce the load on the electricity grid.
NOTE: When enabled and active, this feature takes priority
over the PV feature.
To set the parameters, access the phv menu, by pressing the
