6.2.2 PUMP START/STOP THRESHOLDS
Note: The THRESHOLDS parameters can be set only with a system with a pressure or level sensor.
The thresholds must be set considering the hydraulic performances of the pump (curve Q-H) and of the
type of system.

NOTE: The jockey pump, if present, is not subject to rotation and is started first, it remains on when the
duty pumps start and it switches off last.

Comment
Enable pump rotation.
Set YES to activate pump rotation. Automatic
pump rotation takes place each time the set is
restarted after stopping in automatic mode.
The jockey pump, if present, is not subject to
rotation, so it always starts first.
Insert the duty pump that you want to start
first after electrically switching on the set.
In systems with a jockey, as this is P1, the first
duty pump that can be set can only by P2 or
P3.
If automatic pump rotation does not take place
(the set has never been able to stop), after the
set time a "forced" rotation of the duty pumps
is performed (excluding the jockey).
