Description
 Thermal alarms with block of the respective
pumps and remote signalling.
Indicated with: AL8PI, AL8P2, AL8PS.
3 = 4P.
4 supply pumps
Functions:
 All the supply pumps work on system pressures
set in the reference SetPoint and Differentials.
 Rotation of the starting order of the supply pumps
(the first pump to start is the first pump to stop).
 Weekly anti-blocking test of the supply pumps
with 15 sec. forced operation each (if parameter 5
is enabled). Indicated with: P1TEST, P2TEST,

3 supply pumps
+ 1 backup pump
Functions:
 All the supply pumps work on system pressures
set in the reference SetPoint and Differentials.
 Rotation of the starting order of the supply pumps
(the first pump to start is the first pump to stop).
 Weekly anti-blocking test of only the backup
pump (if parameter 5 is enabled). The backup
pump starts up according to the setting in
parameter 6 (anti-blocking time) and remains

appear on the display.
 Thermal alarms with block of the respective
pumps and remote signalling.
Indicated with: AL8P1, AL8P2, AL8P3, AL8PS.
1 : Relative pressure transmitter
2 : Differential pressure transmitter
Choice of the number of supply pumps that make
up the system:
max two for system type 2
max three for system type 1
max four for system type 3
Choice whether to exclude or insert the pump anti-
blocking test cycle.
