1.1.1 HV input 2 (input configurable to 230 V)
Press the selector . Turn the selector to choose the desired
item.
1 Absent: input not active.
2 DLSG: Input not active (0 V), the heating elements are disabled
in every operating cycle.
3 SG2: input 2 for the Smart Grid Ready protocol (refer to the
paragraph “Standard SG ready”).
4 External switch off signal: switches the machine OFF. Every
heating, cooling and DHW request is interrupted while the
anti-freeze protection logics are active.
5 Photovoltaic integration: input not active (0 V), no integration.
Input active (230 V), the energy surplus is used to increase
the DHW set-point by the quantity defined through parameter
1.20.0 PV offset DHW setpoint temperature. If the
DHW cylinder has reached the new set-point, it is possible
to use this energy to increase the set-point of the inertial
storage tank (if present) through parameter 20.4.4 Buffer
electric integration offset or of the heating / cooling function
to the comfort set-point.
Press the selector to confirm.
1.1.3 AUX input 1
Press the selector . Turn the selector to choose the desired
item.
0 None.
1 Humidistat sensor: when the contact is closed, the heat
pump is turned off during the cooling cycle. Use Par. 1.1.9
Humidity input zone to set the zone pumps that will stop
as a result.
2 Heat / Cool by external control: when the contact is closed,
the operating mode is set to cooling; when the contact is
opened, the operating mode is set to heating.
3 Room thermostat HC3: the signal is interpreted as a contact
for a thermostat in zone 3. When the contact is closed,
it is sent as a heat request for zone 3.
4 Safety thermostat: connect an underfloor safety thermostat
to the contact. When the contact is closed, water circulation
is interrupted.
5 Photovoltaic integration: input not active (contact open),
no integration.
Input active (contact closed), the energy surplus is used
to increase the DHW set-point by the quantity defined
through parameter 1.20.0 PV offset DHW setpoint temperature
- Delta T Setpoint DHW photovoltaic. If the DHW
cylinder has reached the new set-point, it is possible to use
this energy to increase the set-point of the inertial storage
tank (if present) through parameter 20.4.4 Buffer electric
integration offset or of the heating / cooling function to
the comfort set-point.
Press the selector to confirm.

tank (if present) through parameter 20.4.4 Buffer electric
integration offset or of the heating / cooling function to
the comfort set-point.
