The setpoint value for integrated differential-pressure control is
determined for the pump via an analogue signal 0 - 10 V
(see “High-Efficiency Pumps Planning Guide”).
- Remote speed adjustment:
An external controller issues an actuating signal for remote speed
adjustment (DDC operation) (see “High-Efficiency Pumps Planning
Guide”).
The desired function must be activated at the pump.
• DP twin-head-pump interface DP for possible integration twinhead
pump management of 2x single or 1x twin-head pump
