6.6.1 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.
6.6.1.1 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 (located inside the device). The remote connections to
possible energy systems are the responsibility of the qualified
installer (connection boxes, terminals and connection cables).
The following figures give an example of remote connection (fig.
20 and fig. 21) which must not be longer than 3 m.
