Pre-defined applications in the settings assistant
Underfloor heating – Dynamic Adapt plus
For the "Heating with underfloor heating" application, Dynamic Adapt plus provides a
control function that automatically and continuously adjusts the required pump output
based on the requirements of the heating system.
Dynamic Adapt plus does not require setpoint adjustments, the control mode does not re-
quire the design point. The pump continuously adjusts its delivery rate to the require-
ments of the consumer loads and to the status of the open and closed valves and thus re-
duces energy requirements significantly.
Underfloor heating – Hall temperature T-const
For applications, in which the pump supplies only one room/hall with underfloor heating,
there is a temperature control, which not only adjusts the pump output to the temper-
ature requirements of a room/hall, but also controls the temperature of the room/hall.
This control mode does not require hydraulic control valves and prevents hydraulic loss.
In order to control the hall temperature, the pump requires a temperature sensor, which
records the current temperature of the room. For this purpose, commercially available
temperature sensors such as PT1000 sensors can be connected to an analogue input of
the pump.
Ceiling heating – Differential pressure Δp-c
For the "Heating with ceiling heating" application, there is an optimized constant differ-
ential pressure control. Consumer loads with ceiling heating can be supplied with a con-
stant differential pressure control (Δp-c) according to the needs.
Assuming a maximum required delivery head at the design point, the pump variably ad-
justs the pump output to the required volume flow. The volume flow varies through the
open and closed valves at the heating circuits. The pump output is adjusted to the re-
quirements of the consumer load and the energy requirement is reduced.

Fan heater – Differential pressure Δp-v
For the "Heating with fan heater" application, there is an optimized variable differential
pressure control. Consumer loads with connected fan heaters can be supplied with a vari-
able differential pressure control (Δp-v) according to the needs.
Assuming a maximum required delivery head at the design point, the pump variably ad-
justs the differential pressure to the volume flow. The volume flow varies through the
open and closed valves at the consumers. The pump output is adjusted to the require-
ments of the consumer load and the energy requirement is significantly reduced.
