HG01: Burner hysteresis

The burner switching hysteresis regulates the heat generator temperature within a set range by switching
the burner ON and OFF. The higher the start/stop temperature differential, the greater the fluctuation in
heat generator temperature around the set value with correspondingly longer burner runtimes, and vice
versa.
Longer burner runtimes protect the environment and extend the service life of wearing parts.

Time curve of the dynamic burner hysteresis for a user defined burner hysteresis (HG01) of 15°C and a
selected hysteresis time (HG33) of 10 minutes. After the hysteresis time, the burner switches off at the
minimum burner hysteresis (HG60) of 7°C.
7.2.2

HG07: Run-on time, heating circuit pump

If there is no further heat demand from the heating circuit, the feed/heating circuit pump will run on in
accordance with the set time This prevents a safety shutdown at high temperatures.
7.2.3

HG08: Maximum boiler water temperature HTG T-Flowmax

HG08 sets the upper limit of the temperature of the heat generator during heating mode. The burner shuts
down. HG08 has no effect during cylinder heating. The temperature of the heat generator can be higher
during this time. "Reheating effects" can result in the temperature being slightly exceeded.
7.2.4

HG09: Burner cycle block

Each time the burner is shut down in heating mode, it will be disabled for the duration of the burner cycle
block. The burner cycle block is reset by turning the ON/OFF switch off and on or by briefly pressing the
