Control mode:
Variable differential pressure (
Δp-v)
The differential pressure setpoint H is increase linearly over the
permitted volume flow range between 1/2H and H.
The differential pressure generated by the pump is adjusted to the
corresponding differential pressure setpoint. This control mode is
especially useful in heat systems with radiators since the flow noise in
the thermostatic valves are reduced
Constant differential pressure (
Δp-c)
The differential pressure setpoint H is kept constant over the permitted
volume flow range at the set differential pressure setpoint up to the
maximum pump curve.
This control mode is recommended for underfloor-heating circuits or old
heating systems with large size pipes as well as for all applications with
no changeable pipe system curve, e.g. boiler charge pumps.
