1.1 About these instructions
Please read and follow the operating instructions, in particular the safety information
contained therein. Keep them available next to the boiler.
These operating instructions contain important information about operation, electrical
connection and troubleshooting for the Lambdatronic S 3200 control.
NOTICE
The values given in the parameter lists are examples, and
should not be used as standard values!
The constant further development of our products means that there may be minor dif‐
ferences from the pictures and content. If you discover any errors, please let us know.
1.2 Safety information
DANGER
When working on electrical components:
Risk of electrocution!
When work is carried out on electrical components:
❒ Only have work carried out by a qualified electrician
❒ Observe the applicable standards and regulations
➥Work must not be carried out on electrical components by unauthorised
people
WARNING
When touching hot surfaces:
Severe burns are possible on hot surfaces and the flue gas pipe!
When work is carried out on the boiler:
❒ Shut down the boiler in a controlled way (operating status "Off") and allow it to
cool down
❒ Protective gloves must generally be worn for work on the boiler, and it should
only be operated using the handles provided
❒ Insulate the flue pipes or simply avoid touching them during operation.
The information on safety, standards and guidelines in assembly and operating in‐
structions for the boiler should also be observed.

Connecting an isolating valve
If an isolating valve is connected to a speed-controlled pump outlet, an RC element
must be used.
Furthermore, the minimum speed for the pump outlet in use must be set to 100% in
the boiler control system.
Connection example:
The outer cable L(bn) should be connected to the outer cable of the respective mains
supply of the module or to the core module, HCP0/burner relay output at pin “LV”.

2.2.6 Connect the patch cable to the bus plug
To connect a patch cable to a RJ45 bushing and a 5-pin plug, follow the connection
diagram below:
2.2.7 Setting end jumpers
To ensure smooth running of the bus system, the jumper must be placed on the last
module.
End jumper not set End jumper set
If the contacts at the base of the end jumper are not bridged (image left), it is referred
to as “not set". In this case there is no bus termination. If the contacts are closed (im‐
age right), the end jumper is set and the bus connection is terminated.

2.2.8 Setting the module address
For hydraulic modules or heating circuit modules it is necessary to set the required or‐
der with the module addresses. The first board of a module type should always have
the address 0, so that the standard hydraulic systems set do not have to be subse‐
quently configured. For further module types ascending module addresses (address 1
- 7) are set.
A hydraulic module with address 0 is included in standard delivery. If a second hy‐
draulic module is also installed, address 1 is set.
