Fig. 3 Installation of wall-mounting plate
BUS BUS interface connection
3.4 Electrical connection
Power is supplied to the solar controller via the BUS cable.
The wires are insensitive to polarity.
If the maximum total length of the BUS interfaces between all
BUS nodes is exceeded or the BUS system has a ring structure,
commissioning of the system is not possible.
Maximum total length of BUS interfaces:
• 100 m at 0.50 mm2conductor cross-section
• 300 m at 1.50 mm2conductor cross-section.
▶ If several BUS nodes are installed, maintain a minimum
clearance of 100 mm between the individual BUS nodes.
▶ If several BUS nodes are installed, connect the BUS nodes
in series or in a star pattern.
▶ To avoid inductive interference: Make sure all low-voltage
cables are routed separately from mains voltage cables
(min. clearance 100 mm).
▶ In the case of external inductive interferences (e.g. from
photovoltaic systems), use shielded cables (e.g. LIYCY)
and earth the shield on one side. The shield should be
connected to the building's earthing system, e.g. to a free
earth conductor terminal or water pipes, and not to the
grounded terminal in the module.
▶ Make a BUS interface to the solar module.
3.5 Fitting/Removing the controller
Fitting the solar controller
▶ Hook in the solar controller at the top.
▶ Click in the solar controller at the bottom.
Fig. 4 Fitting the solar controller

7.1 Solar system settings
Fig. 8 Solar settings menu
If a solar system with extended functionality is installed,
corresponding menus and menu items become active. The
menus of the solar system are described in detail in the
operating instructions of the module installed (e.g. MS 200).
In the Solar settings menu with all solar systems the sub-
menus listed in Tab. 7 are available.
If the solar collector area is incorrectly set, the solar yield
displayed in the info menu is wrong as well.

7.2 Diagnosis
Fig. 9 Diagnosis menu
The Diagnosis service menu contains a number of tools for
diagnosis. Note that the menu items shown will vary depending
on the heating system.
7.2.1 Function tests
This menu can be used to test active system components
individually. If Enable function tests is set to Yes in this menu,
the normal heating operation is interrupted in the entire
system. All settings are saved. The settings in this menu are only
temporary and revert to the respective default settings as soon
as the Enable function tests is set to No or the Function test
menu is closed. The available functions and the possible
settings vary depending on the system installed.
A function test is performed by setting the parameters of the
listed component accordingly. You can check whether the
mixer, pump or valve responds appropriately by inspecting the
behaviour of the corresponding component.
The solar pump can be tested, for instance:
•Off: The pump stops.
•On: The pump starts.
7.2.2 Monitored values
System settings and measurements are displayed in this menu.
For example, the system can display whether the maximum
collector temperature or the current cylinder temperature has
been reached.
You can also call up detailed information on system parts, e.g.
the swimming pool. The information and values that are
provided depend on the system that has been installed.
Observe the technical documentation for modules and other
system components.
7.2.3 Fault displays
The current faults and the fault history can be called up in this
menu.

8 Thermal disinfection
CAUTION:
Risk of scalding.
Duringthermaldisinfection,dischargingunmixedhotwatercan
cause serious scalding.
▶ Only use the maximum adjustable hot water temperature
for thermal disinfection.
▶ Inform occupants of the premises of the risk of scalding.
▶ Perform thermal disinfection outside of the normal
operating times.
▶ Do not discharge DHW unmixed.
▶ Ensure a thermal mixing valve is fitted as stated in the UK
G3 building regulations.
Perform thermal disinfection/daily heat-up to kill off pathogens
(e.g. legionella) on a regular basis.
To guarantee thermal disinfection/daily heat-up:
▶ Set the heat source (e.g. boiler) in such a way that daily
heat-up can be carried out, for example temperature
settings or time programme for DHW heating.
▶ Install the pipework for system components, which are
necessary for thermal disinfection or daily heat-up, as
energy-efficiently as possible (short pipe lengths, good
thermal insulation, etc.).
In the case of larger DHW systems, there may be statutory
requirements (regulations on drinking water) for thermal
disinfection. Observe the instructions in the technical
documentation of the heat source.

Time correction This correction ( – 20 ... 0... + 20 s) is
automatically carried out once a week (0 is
default).
Example: Deviation of the time by
approximately –6 minutes per year
• –6 minutes per year is equal to
–360 seconds per year
• 1 year = 52 weeks
• –360 seconds: 52 weeks
• –6.92 seconds per week
• Correction factor = +7 s/week.

Troubleshooting
CS200 – 6720830475 (2015/06)
If daily heat-up is activated:
• The entire DHW volume is heated up daily to the
temperature that has been set for the daily heat-up.
This function is not performed, if the domestic hot water
has already reached the set temperature within the last 12
hours due to solar heating.
• The daily heat-up starts automatically at the set time
according to the time set in the solar controller.
9 Troubleshooting
Table 12 During installation enter the ID number of the solar
controller here.
A fault in the system is indicated on the display of the solar
controller. The cause can be a fault on the solar controller, in a
component, in an assembly or on the heat source. The
instructions belonging to the affected component or assembly,
and especially the service manual with detailed fault
descriptions, contain additional information on
troubleshooting.
The solar controller saves the last 20 faults (fault history,
page 12).
Only use original spare parts. Damage resulting from spare
parts, which are not supplied by the manufacturer, is excluded
from liability.
If a fault cannot be corrected, Worcester's Technical Support
