5.6 Electrical connections
The product comes already wired for the mains supply. It is pow-
ered via a flexible cable and a combination plug/socket (fig. 18
and fig. 19). For connection to the mains, a Schuko socket with
ground and separate protection is required.
ATTENTION!: The power supply line to which the
equipment will be connected must be protected
by a suitable differential switch.
The type of differential must be chosen accord-
ing to the type of electrical devices used by the
overall plant.
For the mains connection and the safety devices
(e.g. differential switch), comply with IEC stan-
dard 60364-4-41.

5.6.1 Remote connections
The equipment is prearranged to be connected to other remote
energy systems or energy meters (solar thermal, photovoltaic,
Off-Peak)
INPUTS
•
Digital 1
(DIG1)
. NOT USABLE.
(THE TWO WIRES, WHITE AND BROWN, OF THE 6-CORE
CABLE ARE NOT TO BE USED).
•
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.
