7.21.5 Source of required value

SOURCE REQ. VALUE
Five settings are possible:
OFF, ADR1,ADR2, ADR3 and ADR4. If an additional input (INT or EXT-ADC-I or EXT-ADC-
U) is active, you must select the address where this input is connected.
When Multicontroller or Synch. Controller is active, the actual active value is shown in
brackets in the middle of the display. If the sign "#" is shown in the second line of the
display, the pump will work with a required value from another pump in the multipump
system. On the pump, which is the source of the required value, there is no "#" shown.

7.21.6 Synchronous Control

If the synchronous control is active the activated pumps try to control the set pressure
together (all pumps run at the same frequency). The 2
reaches the release frequency (ENABLE SEQ. CONTR.) The pumps will now maintain
constant pressure by running synchronously. The follow-up pump will stop, when both
pumps together run below the set SYNCHRON. LIMIT. This creates the hysteresis effect.

Switch off threshold of the first follow-up pump. The switch off thresholds of the other
pumps are each higher by the SYNCHRON-WINDOW.
This parameter is also used for the stop value for the external constant speed pump at
activated Simple Multicontroller in the parameter configuration relay.
