Address:
 00 master
 01 to 07 slaves


OFF
Function to allow alternating between
the inverters connected in COMBO (or
pumps connected in DOL) in order to
allow equal use of each pump in the
group; master will reorganize the starting
priority of the pumps by checking the life
of each of them.


0
Maximum difference in terms of hours
between units in the group.
0 stays for 5 minutes.


OFF
With this parameter it is possible to
activate the synchronous operation
(same speed) of the pumps in COMBO.
It is however necessary to appropriately
lower the parameter "f. min. control".


0
Delay time with which the slaves start
after the variable speed pump has
reached the maximum frequency and the
pressure value has fallen below set value
– delta control


Direct
Direct: increasing motor speed also
misured value increases
Reverse: increasing motor speed, misured
value decreases.


0
Pump periodic autorun after XX hours of
inactivity. Value 0 makes function
