check valve; a check valve control device; a safety valve;
a hydraulic load cut-off device.
NB!: The discharge pipe connected to the overpressure
device must be installed in a continuous downward slope
and in a place protected against the formation of ice.
Water may drip from the discharge pipe of the overpres-
sure device and this pipe must be left open to the atmo-
sphere.
ATTENTION!: The heat pump for DHW produc-
tion can heat the water to over 60°C. Therefore,
to protect from burns, an automatic thermostatic
mixing device must be installed on the hot water
piping (fig. 16).

5.5.1 Condensate drain connection

The condensate forming during heat pump operation flows
through a special drain pipe (1/2"G) that passes inside the insu-
lating casing and comes out the side of the equipment.
It must be connected, via a trap, to a duct so that the conden-
sate can flow regularly (fig. 17).

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-
