25. Parameter description
Parameter HG01
Burner
switching hysteresis
The burner switching hysteresis regulates the boiler water temperature within
a set range by switching the burner ON and OFF. The higher the hysteresis,
the higher the boiler water temperature fluctuation around the set value, resulting
in longer burner runtimes and vice versa. Longer burner runtimes protect the
environment and extend the service life of wearing parts.

Control unit parameters
Individual settings: ________
Parameter HG02
Lower burner output
The setting for the minimum burner output (minimum device load) is applicable
to all operating modes. This percentage value corresponds approximately to
the real device output.
Parameter HG03
Upper burner output DHW
The setting for the maximum burner output in DHW mode (maximum device
load). Valid for DHW cylinder heating. This percentage value corresponds
approximately to the real device output.
Parameter HG04
Upper burner output HZ
The setting for the maximum burner output in heating mode (maximum device
load). Valid for heating mode, BMS and emissions test. This percentage value
corresponds approximately to the real device output.
