Pump operating mode 2:
BufferprimarypumpforBSPcylinder
Heating circuit pump become the buffer primary pump.
The manifold sensor (buffer) only affects the heating operation. In case of cylinder
heating, the reference temperature is provided by the internal boiler sensor. In heating
mode, the buffer primary pump runs only when there is a burner demand. Pump run-on
in accordance with parameter HG07.
Subject to there being no heat demand from the heating circuit, the boiler circuit pump
will run on in accordance with the set time, to prevent a boiler safety shutdown at high
temperatures.

Factory setting: 4 min
Setting range: 0 to 30 min
Each time the burner is shut down in heating mode, it will be blocked for the duration
of the burner cycle block.
The burner cycle block is reset by switching the ON/OFF switch OFF and ON or by
briey pressing the reset button.

This function limits the boiler water temperature upwards in heating mode, and the
burner shuts down. This parameter has no function during cylinder heating, and the
boiler water temperature may also be higher during this time. "Reheating effects" can
result in the temperature being slightly exceeded.
