You must isolate the control unit from mains power before carrying out any
assembly or connection work.
The installation and start-up of the control unit should only be carried out by
qualified technical personnel. All work must comply with the applicable national and local safety regulations.
Always ensure that you isolate the
equipment from mains power before
starting installation or connection work
on the unit's electrical components.
Make sure that you never confuse the
SELV (safety extra low voltage) connectors (sensors, flow transmitters) with the
230 V connectors. This may produce
life-threatening current and cause irreparable damage to the device, attached sensors and equipment.
Solar plant can generate high temperatures. There is therefore a risk of burn
injuries! Take care when installing the
temperature sensors!
When installing sensors, avoid locations
(such as heat sources) that generate
temperatures outside the equipment's
maximum range (>50 °C).

Only install the control unit in dry interiors not subject to a risk of explosions.
Do not install the unit onto flammable surfaces.
4.1 Opening the unit
Before opening, ensure the unit is isolated
from mains power. If a locking screw has
been attached to the cover of the unit, you
will need to remove this first. The top of the
casing snaps onto the lower part of the unit
on both sides. You can release the top of
the casing by pulling gently on the sides of
the cover (see picture) and then pivoting the
cover
upwards.
Continue to pull the
cover upwards until
it snaps into place.
This will enable you
to easily install and
connect up the control unit
Before switching on or starting up the system:
ensure you have closed the cover – you must be able to hear
and feel it snap into place! Re-attach the locking screw
4.2 Wall installation
If installing the unit on a wall, proceed as follows:
•
Drill the mounting holes to match the drilling
template provided
•
Screw in the two upper screws so that they project 6 mm from the wall
•
Open the unit as described above and hang it on
to these two screws. You can now screw in the
two lower screws.
•
Tighten all screws only as much as necessary, to avoid damaging the lower part of the
unit casing!

Assembly and Operation Manual
5.1 General connection guidelines:
• When connecting all cables, strip the cable covering to a length of approx. 6-8 cm and the
wires to a length of approx. 10 mm.
• For flexible cables, a strain relief device must be present on the interior or exterior of the unit.
On the 230 V side, this can be done by mounting a max. of 4 M12 cable screws. The ends of
the wires must be covered with wire end ferrules. The cables are fed through the apertures
provided and attached to the unit.
• All earth leads must be attached to the terminals marked "PE" (potential earth).
5.2 230 V connectors
One mains power connector is provided,
plus a total of 6 230 V/50 Hz outlets.
Bear in mind the following points concerning
the 230 V connectors:

i
If the control unit is wired directly into
the mains, it must be possible to isolate
mains power by using a switch external
to the unit.
If the unit is connected using a cable
and earthed plug, this switch is not necessary.
The control unit is designed for use with
230 V/50 Hz mains power. Any attached
pumps and valves must also be rated for
use at this voltage!
i
All switched outputs (A1 to A6) are
electronic 230 V AC make contacts. If
you need potential-free contacts, then
suitable accessory parts can be supplied.
i
Depending on the functional layout
used, all outputs can be used as
switched outputs or – using block
modulation – as pump power controls.
i
All output activity is monitored electronically. A functional check is made
automatically once a day, and can also
be started manually from the "Manual
Operation" menu.
The neutral lead terminals (N) are connected electrically and are not switched!

Assembly and Operation Manual
5.3 Connecting sensors
The control unit works with high-precision platinum PT1000 temperature sensors. Between 2
and 10 sensors will be needed, depending on the system setup and functional layout. In some
layouts, the use of radiation sensors and flow transmitters will also be required. Inputs 1 to 7
are suitable for temperature sensors. Inputs 8 to 10 are universal inputs, which can be used for
temperature sensors, radiation sensors or digital inputs.
Temperature sensor installation / cabling:
§ Mount the sensors in the corresponding
places on the collector and storage
tank. When doing so, ensure good temperature transfer, using heat-conductive
paste if necessary.
§ The temperature sensor cabling can be
extended if required. Cross-sections required: lengths up to 15 m, 2 x 0.5 mm²;
lengths up to 50 m, 2 x 0.75 mm². Use
shielded extension cables for long connections
(e.g.
to
collector).
Do not insert shielded cable on the
sensor side – clip it and strip it!
§ Temperature sensors are connected
according to the system setup. You do
not need to observe polarity for the two
wires when cabling temperature sensors.
When laying sensor cabling, keep it
away from 230 V cables: these can be a
source of electrical interference under
adverse conditions. Keep cabling at
least 15 cm apart.
5.4 Surge protection module
The control unit is provided with fine-level surge protection for all sensor inputs. As a
rule, you will not need to take additional precautions for interior sensors. However, we
recommend additional protection for collector sensors and exterior sensors (sensor
connection box with surge protection). Exterior protective devices must not contain
any additional capacitors, since these may distort measurement readings.

This menu can be used to check and
change all configurable parameters. As a
rule, the factory settings generally configure
the parameters so as to guarantee the
smooth operation of the system.
Values displayed will depend on the unit
type and the ancillary features configured.
Only the values required for the unit are displayed.
Complex system set-ups need many parameters to be programmed. To keep the
operation of the unit as simple as possible,
these parameters have been grouped into

on the system setup selected and the ancillary features configured.
7.4 "Manual operation" menu
The solar power system can be operated
manually for servicing and testing. This also
lets you switch on/off the 230 V switched
outputs. No automated control of the system
is available during manual operation. To
prevent system instability, the system
switches back to "Display" mode after
approx. 8 hours in manual mode, reactivating automated control.
The option "Follow-on manual" can be used
to set manual operation for a set period.
During this time, you can exit from the

The control unit is equipped with an innovative data interface. This interface enables the following optional functions:
Data logging (with DataStick®)
Remote system monitoring (with modem package)
These functions are optional. To use them, you will need extra accessories (not supplied
with the unit) such as a DataStick or modem!
9.1 DataStick®
A DataStick provides a simple way to carry out data exchange between the control unit and a
PC. The system has the advantage that the PC does not need to be connected to the control
unit itself, meaning that even a desktop PC can be used. Data is stored indefinitely on the
DataStick® – even without power.
The DataStick® can be connected or disconnected to the port on the top of the unit without disturbing unit functionality; no special tools are required.
9.2 Data logging
By using a DataStick, all system status, measurement and error message data can be recorded
at intervals of 1-30 minutes (configurable) and then transferred to a standard PC. Each data
record also contains the date and time of day.
Over 16,000 data records can be saved to the DataStick.
Recording times depend on the configured recording interval, as follows:
Interval
1 minute
5 minutes
30 minutes
Approx. max.
time
11 days
55 days
350 days
The recording function starts automatically once the DataStick is inserted.
Parameters are stored on the DataStick itself and can be modified as needed using "Data logging" on the "Programming" menu:
Recording interval configuration
Selection of simple recording (storage medium is written to until full) or cyclical recording
(old data is overwritten)
Reset logging storage (any data present is deleted, unit reboots)
Accessories required:
PC software for evaluating the data recorded
PC interface adapter for the USB port
