2.1.5 Boiler enable contact
When commissioning the boiler using the settings wizard, the boiler release contact function (“
How is the
boiler release contact on the core module being used?
”) is called up to enable the optional
analysis of an external floating release or start contact. The following functions are possible depending on the
setting and electrical connection:

not in use
No effect on boiler operation (contact must not be clamped/
bridged).
Release/disable boiler
As long as the boiler release contact is closed, the boiler controller
operates according to the specified parameters (mode, time
window, etc.). If the boiler release contact is opened, the boiler is
no longer released and follows the shutdown procedure. As long as
the boiler release 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 release contact is open, the boiler controller
operates according to the specified parameters. If the boiler release
contact is closed, the boiler starts in continuous load operation (e.g.
heat requirements of a heating fan).
