25. Parameter description

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.
Set switching hysteresis 15 °C

Fig.:
Time sequence of the dynamic burner switching hysteresis for a user-defined
burner switching hysteresis of 15 °C and a selected hysteresis time (parameter
HG33) of 10 minutes.
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.
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.
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.
Hysteresis time 10 minutes
