4 | Product Description
▶ Due to the additional functions, e.g. DHW heating or pump
anti-seizure protection, the system should always be left
on.
▶ Correct any faults immediately.
2 Product Description
2.1 Product description
• The CS 200 must be used in conjunction with the
MS 200 to control a Solar heating system, in certain
cases an MS 100 may also be combined.
• After operating for 90 minutes, the solar controller has a
power reserve of at least 8 hours. If the power failure lasts
longer than the power reserve, the time and date will be
deleted. All other settings are saved.
• The functional scope and thus the menu structure of the
solar controller are determined by the structure of the
system. These instructions describe the maximum
functional scope of the equipment. Your attention is drawn
to the importance of the system structure in the relevant
places. The adjustment ranges and default settings may
differ from the information in these instructions.
2.2 Important information on use
CAUTION:
Risk of injury through scalding!
If the DHW temperature is set to > 60 °C, discharging unmixed
domestic hot water can lead to serious scalding.
▶ Set the temperature for normal operation to < 60 °C.
▶ Do not discharge domestic hot water unmixed.
▶ Install a mixer.
• Only products from Bosch may be used within the BUS
system.
• The installation room must be appropriate for IP20 rating.
2.3 Declaration of Conformity
The design and operation of this product comply
with European Directives and the supplementary
national requirements. Conformity has been
demonstrated by the CE marking .
You can ask for a copy of the Declaration of Conformity for this
product. Please refer to the contact address on the back cover
of these instructions.

2.6 Temperature sensor characteristics
When measuring temperature sensors, observe the following
requirements:
• Isolate the system before measuring.
• Measure the resistance at the cable ends.
• The resistance values represent average values and are
subject to tolerances.

sensors in solar system except collector temperature
sensors)

2.7 Additional accessories
For precise information regarding suitable accessories, refer to
the manufacturer's product literature.
Function modules and user interfaces of the control system
EMS 2:
• MS 100: Module for solar system or freshwater station
• MS 200: Module for extended solar systems or transfer
system.
2.8 Disposal
▶ Dispose of packaging in an environmentally responsible
manner.
▶ When replacing assemblies or components, dispose of the
old assemblies or components in an environmentally
responsible manner.
3 Installation
The detailed system schematics for installation of the hydraulic
assemblies and components and the associated control
devices can be found in the technical guides or tender
specifications.
CAUTION:
Risk of injury through scalding!
If the DHW temperature is set to > 60 °C, discharging unmixed
domestic hot water can lead to serious scalding.
▶ Set the temperature for normal operation to < 60 °C.
▶ Do not discharge domestic hot water unmixed.
▶ Install a mixer.
WARNING:
Risk to life from electric shock!
Touching live parts can result in an electric shock.
▶ Before installing accessories: Disconnect the power supply
to the heat source, building management system and any
other BUS nodes (all poles) and secure against
unauthorised or accidental reconnection.
3.1 Types of installation
The installation of the solar controller depends on its use and
the solar heating system design ( Chapter 2, page 4).
3.2 Installation location of the solar controller
For direct and easily accessible operation we recommend the
installation of the solar controller in the living space.
3.3 Installation in the reference room
The installation surface on the wall must be flat.
▶ Install wall-mounting plate ( Fig. 3).

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 mm
2
conductor cross-section
• 300 m at 1.50 mm
2
conductor 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
Removing the solar controller
▶ Press the button on the underside of the mounting plate.
▶ Pull the bottom of the solar controller away from the plate.
