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 "Boiler off") and al‐
low 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.

2.1.6 Boiler enable input
When setting the system type, the parameter "Boiler enable input available" is preset
to enable potential analysis of an external floating release or start contact.
Boiler enable input available YES
This is set if the boiler enable input is available.
As long as the contact is closed, the controls operate according to the speci‐
fied operating mode. If the external contact is opened, the boiler loses the
enable and follows the shutdown procedure.
As soon as the handle is opened, the controls cease to accept any heat re‐
quirement
(e.g. flue gas thermostat of a supply boiler).
Boiler enable input available NO
This is set if there is a boiler start input or no allocation.
As long as the contact is open, the controls operate according to the speci‐
fied parameters. If the external contact is closed, the boiler starts and works
in continuous operation.
(e.g. heat requirements of a heating fan)
Note: No handle required for operation.
❒If the boiler is enabled or started by the parameter, it goes at least to "Heating"
status, even if the signal has stopped in the meantime. Only then does the boiler
follow the shutdown procedure.

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”.
