1 S AFETY INSTRUCTIONS
This control unit must be disconnected from the mains before any
installation and wiring work is carried out.
This device may only be opened, connected and commissioned by trained
personnel. In so doing, the relevant safety regulations of your country must
be adhered to.
•Prior to any installation or wiring
work on the electric motors, always
fully disconnect the device from the
operating voltage and ensure that the
mains supply cannot be reactivated.
Never mix up the connections for the
protective safety low voltage area
(sensor, flow meter) with the 230 V
connections. This could result in
damage and hazardous voltages to the
device itself and to the attached sensors
and devices.
•Solar thermal systems can become very
hot. There is a risk of being burnt. Take
care when installing the temperature
sensor.
•Install the Solareg Vision Plus in such a
way that no excessive operating
temperatures (>50°C) result, e.g. as a
result of heat sources.
•The device is not protected against
splashing and dripping. You should
therefore install it in a dry location.
•For safety reasons, the system may be
manually operated only for test
purposes. In this operating mode, there
is no monitoring of maximum
temperatures or sensor functions.
•If there are signs of damage to the
control unit, cables or attached pumps
and valves, the systems must not be
operated.
•Check whether the materials used for
the piping, thermal insulation, pumps
and valves are suitable for the
temperatures that will occur in the
system.
If you have any questions concerning your solar thermal system or your control unit, please
contact your installer or supplier for advice.

Term explanations
Unit A unit is a component of a system and is responsible for part of its
function.
Hysteresis In control technology, the term hysteresis is used where an upper and lower threshold value is responsible for switching (see Td Start and Td
Stop).
Shield Electrical shields reduce the influence of electrical and magnetic fields on the signals in the cables and wires. Coaxial cables are commonly used
for this purpose.
Heat station Place at which energy is stored or transferred. In solar thermal systems,
the storage cylinder is the heat station.

Important notice concerning the valves in diagrams type 1 and type 3:
The system diagrams are propositions.
Regardless of the valve type shown above please follow this instructions:
Type1: one collector, two storages with valve:
•If not powered, the valve should connect the collector array with the storage 1.
•When powered, the valve must connect the collector array with the storage 2.
Type3: two collectors, one storage with valve:
•If not powered, the valve should connect the collector array 1 with the storage.
•When powered, the valve must connect the collector array 2 with the storage.
4.1.1 Over voltage protection
Prior to switching on or commissioning, you must ensure that the cover is
closed properly such that you feel and hear it click into position on both
sides.
SOLAREG II has integrated over voltage protection on every sensor input. Additional
safety measures are usually not required. For the collector sensor an additional
protection item is recommended and can be obtained from Prozeda GmbH. External
protection devices containing capacitors are not allowed as they will distort the
measurement.

5 D EVICE INSTALLATION
This contro
l unit may be installed only in dry rooms where there is no risk of
explosion. Installation on a flammable base is not permitted.
5.1 Opening the device (only by qualified personnel)
No tools are required to open the device.
The upper part of the casing is locked to the
lower part at two engagement points. The
locking forces are such as to prevent the
casing from being opened accidentally.
Holding the casing at each side, pull firmly towards you and then raise the top part of the
casing until it engages. You can now install and wire up the control unit.
Prior to switching on or commissioning, you must ensure that the cover is
closed properly such that you feel and hear it click into position on both
sides.

proceed as follows:
•Drill the fixing holes using the drilling
template shown.
•Screw in the two top screws leaving
a gap of up to 6 mm.
•Open the device as described and
hang it on the two screws. You can
now fit the two bottom screws.
•To avoid damage to the lower part
of the casing, do not over tighten
any of the screws.

General attachment regulations:
For all attachment wires, cut the wire sheath
to a length of approx. 6 – 8 cm and
unisolate the wires by approx. 10 mm from
the ends.
•In the case of flexible cables, provision
must be made inside or outside the
device for strain relief. The wire ends
must be fitted with wire-end sleeves. If
necessary, PG9 screw fittings can be
used for the feedthrough on the 230 V
side.
•The wires are fed into the device
through the designated openings.
•All earth wires must be fixed in the
terminals indicated with “PE” (Earth
potential).
6.1 230 V connections
The following points must be observed for
the 230 V connections:
•Where there is a fixed mains
connection, it must be possible to
interrupt the mains supply to the control
unit outside the control unit by means of
a switch.
Where the mains connection is effected
by means of wire and plug with earthing
contact, this switch may be dispensed
with.
•The control units are designed for
operation with a 230 V /50 Hz mains
supply. The pumps and valves to be
connected must be designed for this
voltage.
•All earth wires must be connected to the
terminals marked PE.
i The neutral terminals (N) are electrically
connected and are not switched.
i The switching outputs (A1/A3) are 230
V closers.
6.1.1 Overview: 230 V connections for Solareg Vision Plus
The table below shows the allocation of
switching outputs for the different system
types. The fields with a grey background are
essential to the basic functions of the
system. The white fields are designed for
optional additional functions:

The Solareg Vision Plus devices work with precise platinum temperature sensors of type
PT1000. Between 3 and 4 sensors are required, depending on the scope of function.
Installation/wiring of temperature sensor:
Install the sensors at the requisite places
on the collector and the storage cylinder.
In so doing, ensure good temperature
transmission and, if necessary, use a
thermally conductive paste.
The cables of the temperature sensors
can be extended. For lengths up to 15 m,
a cross-section of 2 x 0.5 mm² is
required; for lengths up to 50 m, a cross-
section of 2 x 0.75 mm² is necessary. In
the case of long connections (collector),
shielded extension cables must be used.
Do not attach the shield on the sensor
side; instead cut it to length and insulate
it.
To protect the collector sensor within the
control unit, the use of a lightning
protection device (accessories) is
recommended.
The temperature sensors are connected
in accordance with the system diagram.
In the case of temperature sensors, there
is no need to observe the polarity of the
two wires.
To protect the collector sensor within the
control unit, the use of a lightning
protection device (accessories) is
recommended.
Sensor wiring must be laid separately
from 230 V wires.
The sensors TTh, Td1 and TFrost can be freely assigned in the „Basic settings“ menu.
