Humidity sensor: when the contact is closed, the heat
pump is turned off during the cooling cycle. Use Par.
1.1.9 to set which zone pumps will stop as a result.
2
Heating/Cooling from External Request mode: when
the contact is closed, the operating mode is set to cool-
ing; when the contact is opened, the operating mode is
set to heating.
3
Thermostat TA3: 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 under-floor safety ther-
mostat to the contact. When the contact is closed, wa-
ter circulation is interrupted.
5
Photovoltaic input active: input not active (0V), no inte-
gration.
Input active (230 V), the energy surplus is used to in-
crease the DHW set-point by the quantity defined
through parameter 1.20.0 - Delta T Setpoint DHW pho-
tovoltaic. If the DHW calorifier 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 or of the heating / cooling function to
the comfort set-point.
