To reduce the thermal load on the burner the boiler nominal value increase can, in
the heating mode, be limited by a ramp function. This prevents large load jumps up-
wards.
The ramp function can be switched on in a range from 1 K/min to 15 K/min. A nominal
value, calculated from the controller algorithm, will then be limited by this value during
nominal value jumps upwards.

P532 Heating characteristic line gradient direct heating circuit with connected external tem-
perature sensor (see fig. 6-12).
This function permits manual adaption of the heating characteristic line to the building
and the individual demands with weather-dependent control.

P541 Limiting the maximum heating output in room heating mode
The output limitation does not affect the hot water operating mode.
Setting changes must be entered on the setting identification plate and in the operat-
ing handbook. 0% = Q
