1.1.1 HV input 2 (input configurable to 230 V)<br />
Press the selector . Turn the selector to choose the desired<br />
item.<br />
1 Absent: input not active.<br />
2 DLSG: Input not active (0 V), the heating elements are disabled<br />
in every operating cycle.<br />
3 SG2: input 2 for the Smart Grid Ready protocol (refer to the<br />
paragraph “Standard SG ready”).<br />
4 External switch off signal: switches the machine OFF. Every<br />
heating, cooling and DHW request is interrupted while the<br />
anti-freeze protection logics are active.<br />
5 Photovoltaic integration: input not active (0 V), no integration.<br />
Input active (230 V), the energy surplus is used to increase<br />
the DHW set-point by the quantity defined through parameter<br />
1.20.0 PV offset DHW setpoint temperature. If the<br />
DHW cylinder has reached the new set-point, it is possible<br />
to use this energy to increase the set-point of the inertial<br />
storage tank (if present) through parameter 20.4.4 Buffer<br />
electric integration offset or of the heating / cooling function<br />
to the comfort set-point.<br />

1.1.3 AUX input 1<br />
Press the selector . Turn the selector to choose the desired<br />
item.<br />
0 None.<br />
1 Humidistat sensor: when the contact is closed, the heat<br />
pump is turned off during the cooling cycle. Use Par. 1.1.9<br />
Humidity input zone to set the zone pumps that will stop<br />
as a result.<br />
2 Heat / Cool by external control: when the contact is closed,<br />
the operating mode is set to cooling; when the contact is<br />
opened, the operating mode is set to heating.<br />
3 Room thermostat HC3: the signal is interpreted as a contact<br />
for a thermostat in zone 3. When the contact is closed,<br />
it is sent as a heat request for zone 3.<br />
4 Safety thermostat: connect an underfloor safety thermostat<br />
to the contact. When the contact is closed, water circulation<br />
is interrupted.<br />
5 Photovoltaic integration: input not active (contact open),<br />
no integration.<br />
Input active (contact closed), the energy surplus is used<br />
to increase the DHW set-point by the quantity defined<br />
through parameter 1.20.0 PV offset DHW setpoint temperature<br />
- Delta T Setpoint DHW photovoltaic. If the DHW<br />
cylinder has reached the new set-point, it is possible to use<br />
this energy to increase the set-point of the inertial storage<br />
tank (if present) through parameter 20.4.4 Buffer electric<br />
integration offset or of the heating / cooling function to<br />
the comfort set-point.<br />
