1 Application / characteristics and features
1.1 Description and application
The Sunny Scout BASIC fs controllers are powerful microprocessor appliances for
the accurate control of solar systems. They are suitable for most types of south facing solar thermal systems
These solar controllers are for use in either residential, business or industrial premises and should be mounted in dry spaces.
The installer should ensure that the controller meets all necessary regulations and
is suitable for the application prior to installation.
1.2 Controller characteristics

Intuitive menu-conducted operation with graphic symbols and four operating ◼
keys
Temperature dierential regulation - digitally adjustable values ◼
Operating hour meter for storage tank charging ◼
Pump speed modulation & manual switch control of solar circulation pump ◼
Continual system monitoring with error and failure display through symbols ◼
All adjusted values are stored even in the case of any longer mains voltage- ◼
breakdown.
Various protective functions, such as system protection, collector protection, ◼
recooling and ow monitoring
Large wiring space ◼
Available accessories:
Temperature sensor PT1000 ◼
Sensor connection box ◼
Immersion sleeves ◼
2 Safety instructions
Disconnect all appliances from the mains operating voltage completely before ◼
any installation or wiring work is commenced. Ensure that mains voltage is not
connected into the ‘low voltage terminals’ (see page 10). Destruction and extremely dangerous voltages will occur in the controller, connected sensors and
other system components if this is NOT complied with.
Solar systems can absorb extremely high temperatures. There is a danger and ◼
risk of burning! Be careful during the installation of all temperature sensors!
Mount the solar controller in a position to ensure that inadmissible operating ◼
temperatures (>50°C) are not experienced e.g. through other sources of heat.For
safety the system can remain in a ‘manual only’ state for testing purposes. In this
operating mode maximum temperatures or sensor functions are not monitored.
If any damage is seen in/on the controller, wiring cable or connected pumps and
valves the system must not be started.
All installation and wiring
work must only be carried
out on the controller when the
device is disconnected from the
power supply.
The Sunny Scout BASIC fs must
only be connected and commissioned by qualified personnel. In
doing so, the applicable safety
regulations must be observed.

3 Controller installation
3.1 Opening the controller
Prior to opening the device, make sure to disconnect the power supply and ensure
that it cannot be switched back on again.
The top cover is held in place by two catches on the base which can be unlocked by
pulling apart the sides of the top cover (see the picture).
Hinge open the top cover upwards until it is latched into position.
You can now freely install and wire the controller.
3.2 Wall installation
The device is mounted on the marked points. A drilling template is provided with
the device. Insert the "Quick Info" card provided with the device into the pocket
provided on the back of the device. The "Quick Info" card provides the user with an
overview of the functions to facilitate rapid device operation.
The controller MUST be
installed only in dry, non
explosive locations. Installation
should NOT be made onto
combustible materials.
Prior to powering up the
controller ensure that the
top cover is securely latched back
into place

3.3 Electrical connection - overview
For 230V~ connections please note the following points:
◼ I The mains supply voltage to the controller should be provided by a switched
FCU with a 3 amp rated fuse.
Controllers are intended use with 230V~ /50Hz mains. All pumps and valves ◼
should be similarly rated.
All earthed wires must be connected to terminals marked with PE. ◼
Neutral terminals (N) are electrically connected and are not switched! ◼
The switching output (A1) is 230V~ closer. If potential-free contacts are needed, ◼
appropriate accessories are available.
3.4 Sensors connection
The SOLAREG II BASIC controllers work with precise platinum-temperature sensors
type PT1000. 2 sensors are required, the third sensor is optional.
Installation / cabling of the temperature sensors:
◼ Mount the sensors into the collector and storage tank. Ensure proper heat trans-
fer and use heat-conducting paste if necessary.
Cross-sections for cable extensions: ◼
- up to 15m 2 x 0.5mm2,
- up to 50m 2 x 0.75mm2.
If shielded - the shield must be connected to the earth (PE)
Connect the temperature sensors according the systems design and functional- ◼
ity required. Polarity may be ignored as they will operate when tted into either
pole of the terminal.
◼ Temperature sensor cables MUST be run separately from 230V~wires.
It is recommended that the external collector sensor can be additionally pro- ◼
tected by a ‘Collector Sensor Protection Box’ which will protect the system from
over-voltage caused by a lightning strike.

7.2 Protection functions
The controller is equipped with the following protective functions.
7.2.1 Collector protection
If the storage tank is charged to the maximum temperature and the collector temperature exceeds the adjusted collector protection temperature, the solar circuit
pump is turned on. The solar circuit pump is switched o once the collector temperature is 10K below the adjusted value.
In this case, the storage tank is charged up to 95°C regardless of it’s adjusted maximum temperature.
7.2.2 Re-cooling (Holiday function)
The collector protection function is only eective if the storage tank temperature is
below the temperature limit (95°). Therefore, during the holiday period, for example, the storage tank is discharged at night to the adjusted recooling temperature.
