7.2 Operating modes
7.2.1 Information on settings
For common applications such as two-pipe systems Proportional-pressure Control (Δp-
v) is the recommended operating mode. This operating mode offers an extended
control range with additional potential savings compared to Constant-pressure
Control (Δp-c). Depending on the balancing of branch circuits, undersupply may
occur at a consumer installation.
Constant-pressure Control operating mode (Δp‐c) can optionally be selected for
underfloor heating systems, for example. If noises are audible at low flow rates,
select the Proportional-pressure Control operating mode (Δp-v).
The setting of the discharge head setpoint depends on the piping curve of the system
and on the heat requirements. As standard the pump set is pre-set to Proportional-
pressure Control (Δp-v) operating mode.
