6.7.1 Remote connections
The equipment is designed to be connected to other remote
energy systems or energy meters (solar thermal, photovoltaic,
Off-Peak)
INPUTS
• Digital 1 (DIG1). Digital input for solar thermal (only for mod-
els PCV3). In case of a solar thermal system with dedicated
control unit, the latter can be connected to the equipment to
deactivate the heat pump when there is energy production
from solar source. Having a voltage-free contact that closes
when the solar system is active, it can be connected to the
two white and brown wires of the 6-core cable supplied with
the equipment.
Set the parameter P16 = 1 to activate the supplement with
solar thermal.
• Digital 2 (DIG2). Digital input for photovoltaic. In case of a
photovoltaic system connected to the plant, it can be used
to subtract energy in the form of hot water in times of over-
production. If there is a voltage-free contact, e.g. from the in-
verter, which closes when there is overproduction of energy,
it can be connected to the two green and yellow wires of the
6-core cable supplied with the.equipment.
Set the parameter P23 = 1 to activate the supplement with
photovoltaic.
• Digital 3 (DIG3). Input for Off-Peak. This function, available
only in some countries, allows the equipment to be activated
only when there is a signal coming from outside with prefer-
ential tariff. If the electric contactor has a voltage-free contact
which closes when the preferential tariff is available, it can be
connected to the two gray and pink wires of the 6-core cable
supplied with the equipment.
Set the parameter P24 = 1 to activate Off-peak in ECO mode
or P24 = 2 for Off-peak in AUTO mode.
• Digital input (LPSW) for the flow switch of the solar thermal/
DHW circulating pump (not supplied)
• Analog input (PT1000) for solar collector probe.
OUTPUTS
230 Vac - 16 A relay output with N.O. contact. for solar thermal /
DHW recirculation circulating pump (ON/OFF type).
230 Vac - 5 A relay output with contact N.O. for solar collector
shutter / drain valve.
Only for models PCV3

Note: For more information on remote connections and the
configuration of the equipment with these systems, see the
par. "7.5 Operating mode" and "8.1.1 List of equipment
parameters".
6.7.1.1 Remote connection
For the connection to the digital inputs the equipment is sup-
plied with an additional 6-core cable already connected to the
PCBA of the user interface (located inside the device). The re-
mote connections to possible energy systems are the responsi-
bility of the qualified installer (connection boxes, terminals and
connection cables).
The following figures give an example of remote connection (fig.
24 and fig. 25) which must not be longer than 3 m.
