10.8.5 Pump overrun and mixing valve overrun
To protect the boiler against overtemperatures after the burner has shut down, a con-
sumer overrun time can be set on the boiler controller.
10.8.6 Pump kick and valve kick
The pump kick is a protective function that is carried out periodically. It prevents pumps
and/or mixing valves from seizing after longer off periods.
10.9 Heat demand
The internal heating circuit can be connected either directly to the main header (heat
distribution zone) or downstream from the primary controller (heat distribution zone on
the consumer side if a primary controller is present).
This can be parameterized with the following setting:
