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.

5.6.1.1 Remote connection
For the connection to the digital inputs of the equipment, pro-
ceed as follows:
• Disconnect the power to the equipment.
• Remove the bottom cover.
• Connect the 6-core cable, supplied with the equipment, to
connector CN5 on the power board.
• Secure the cable on the free jumper next to the power one.
• Use one of the two free cable glands present near the power
cable for correct anchoring of the cable for the remote con-
nection.
• Refit the bottom cover.
The following figures give an example of remote connection (fig.
20 and fig. 21)which must not be longer than 3 m.
