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 include important information about operation, electrical connection and
troubleshooting. The parameters shown depend on the set boiler type and the system configuration!
The constant further development of our products means that there may be minor differences from the pictures
and content. If you discover any errors, please let us know: [email protected].
1.2 Safety information
DANGER
When working on electrical components:
Risk of electrocution!
When work is carried out on electrical components:
❒ Always 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 persons
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 according to procedure (“Boiler off” operating status) and allow it to

2.1.5 Boiler enable contact
When commissioning the boiler system using the settings wizards, the parameter “How is the boiler enable
contact on the core module being used?” is called up to enable potential analysis of an external floating release
or start contact. The following functions are possible depending on the setting and electrical connection:
Connection position Setting Description
not in use No effect on boiler operation (contact must not be clamped/bridged)
Enable/disable boiler As long as the boiler enable contact is closed, the boiler controller
operates according to the specified parameters (mode, time
window, etc.). If the boiler enable contact is opened, the boiler
loses the enable and follows the shutdown procedure. As long as
the boiler enable contact is open, heating requirements are
ignored. (e.g. flue gas thermostat of a supply boiler, house
distribution box)
Extra heating As long as the boiler enable contact is open, the boiler controller
operates according to the specified parameters. If the boiler enable
contact is closed, the boiler starts in continuous load operation (e.g.
heat requirements of a heating fan).

External power demand 0-10V
You can define an external power demand for the boiler via the analogue module using a 0-10V signal. The type
of power demand can be set using the “Source for ext. power demand (0 – off, 1 – 0-10V, 2
– modbus)” parameter. If 0-10V is selected as the source, the boiler enable mechanism can be controlled via
an adjustable input at the analogue module. If the signal at the input is above 35%, the boiler starts in
continuous load mode; if the signal drops below 30%, the boiler shuts down. By default 0V = 0% and 10V =
100%. This can be changed using the “Invert ext. power demand via analogue input” parameter.
In order to start the boiler via the power request, “Automatic” mode must be set and the release contact (if in
use) must be closed.
Necessary parameters for the parameterisation of the power demand are in the menu “ Boiler – General
settings ”
