Delta control
p = XXX.X [bar]
0.1
This parameter communicates by how much the measured
value must fall in relation to the set value so that the pump,
during shutdown in control ramp, is restarted.

Delta stop
p = XX.X [bar]
0.5
This parameter represents the increment of the measured val-
ue with respect to the set value that must be exceeded so that
a forced shutdown of the pump according to the stop ramp can
occur.

COMBO
ON/OFF
OFF
Enable the function COMBO for the combined operation of
several pumps in parallel. Read the dedicated chapter.

Device address when in COMBO mode:
• 0: master
• 01 to 07: slave

Alternance
ON/OFF
ON
Enabling the alternation between units in COMBO and D.O.L.
The order of priority of operation is alternated based on the
previous start-up of each pump in order to obtain an almost
uniform wear of the pumps.

Alternance period
t = XX [h]
0
Maximum difference in operating hours between multiple devi-
ces in the unit.
0 means 5 minutes.

COMBO synchrony
ON/OFF
OFF
Through this parameter it is possible to activate the synchro-
nous operation of the pumps in COMBO. Read the dedicated
chapter.
However, it is necessary to lower parameter Frequency min
controlaccordingly.

Start delay AUX
t = XX [s]
00
Time delay with which the pumps in a group start up after
the variable speed pump has reached the maximum motor
frequency and the measured value has fallen below the differ-
ence Set value - Delta control.
x
x
x
PI control
Direct/Reverse
Direct
PI control mode:
• Direct: as the pump speed increases, the measured value
increases.
• Reverse: as the pump speed increases, the measured value
decreases.

Periodic autorun
t = XX [h]

Periodic pump start-up after X hours of inactivity. The value 0
disables the function.

Restarts delay
t = XX [min]
10
Time base that establishes the delay of attempts to restart the
pump following a no-water alarm. With each attempt, the delay
time is doubled. The maximum number of attempts is 5.
