Setback operation
When setback operation is enabled, the pump follows the set-
back operation of the heating system with electronic evalua-
tion of a temperature sensor. It then switches to minimum
speed. When the heat generator heats up again, the pump
switches back to the pre-set setpoint stage.
When the setback operation is used, the pump must be
installed in the feed of the heating system.
Dynamic Adapt:
Dynamic Adapt is the dynamic adaptation of the setpoint in the
pump's partial load range at less than half of the intended flow
volume. Starting from the set value, the pump analyses the heat
requirement, and, based on this analysis, the established set-
point is continuously corrected operating in partial load mode.
In this way, the pump output in a control range (Fig. 2a) is con-
tinuously optimised up to the energetic minimum. For very
small volume flows, the pump goes into a hydraulic standby for
this. If the volume flow increases due to higher heat require-
ment, the performance will increase automatically. The short
reaction time prevents the heating system from being under-
supplied.
Venting routine:
The duration of the venting routine is 10 minutes after activa-
tion; it is shown with a countdown in the display.
Key lock (hold function):
The key lock locks the settings on the pump, thus protecting it
from unintended or unauthorized adjustments to the pump.
