17. Parameter description

The burner switching hysteresis regulates the boiler water temperature within the
set range by switching the burner on and off. The higher the start / stop temperature
differential is set, the greater the boiler water temperature fluctuation around the set
value with concurrent longer burner runtimes and vice versa. Longer burner runtimes
protect the environment and extend the service life of wearing parts.
The setting for the minimum burner output (minimum appliance load) is applicable
to all operating modes. This percentage value corresponds approximately to the real
device output.
This setting may only be modified by qualified personnel, as faults may otherwise
result.
The setting for the maximum burner output in DHW mode (maximum appliance
load). Applies to buffer cylinder charging and combi mode. This percentage value
corresponds approximately to the real device output.
The setting for the maximum burner output in heating mode (maximum appliance
load). Applies to heating mode, cascade and emissions test. This percentage value
corresponds approximately to the real device output.
If there is no longer a heat demand from the heating circuit, the internal appliance
pump runs on for the set amount of time, to prevent a boiler safety shutdown due to
high temperatures.
This function limits the upper boiler water temperature in heating mode and shuts the
burner down. During cylinder heating, this parameter has no effect, the boiler water
temperature may therefore be higher during this time. "Reheating effects" can result in
the temperature being slightly exceeded.
