24.Parameterdescription
The setting for minimum burner output (minimum appliance load) is applicable
to all operating modes. This percentage value corresponds approximately to
the real appliance output.

Parameter HG02
Lower burner output
Factory setting: see table
Setting range: 1 to 100 %
Individualsetting:_____
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 appliance output.
Parameter HG03
Upper burner output DHW
Factory setting: see table
Setting range: 1 to 100 %
Individualsetting:_____
The setting for the maximum burner output in heating mode (maximum appli-
ance load). Applies to heating mode, cascade, BMS and emissions test. This
percentage value corresponds approximately to the real appliance output.
Parameter HG04
Upper burner output HZ
Factory setting: see table
Setting range: 1 to 100 %
Individualsetting:_____
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willbetheuctuationinboilerwater
temperature around the set value with corresponding longer burner runtimes,
and vice versa. Longer burner runtimes protect the environment and extend
the service life of wearing parts.
Parameter HG01

switching hysteresis of 15 °C and a selected hysteresis time (parameter HG33)
of 10 minutes. After expiry of the hysteresis time, the burner switches off at the
minimum switching hysteresis (parameter HG60).
