THE ELECTRONIC CIRCULATOR
(low-consumption pump)
The product has a circulator with an electronic motor to save
electricity and comply with the European regulations.
Electronic control of operation:
a) Control mode p – c
In this mode, the electronic controller keeps the differential
pressure generated by the pump at a constant set value of H s.
Pressure differential
b) Control mode p – v
In this mode, the electronic controller varies the pressure
differential between the set value Hs and 1/2 H s. The pressure
differential varies with the volume ow.
Pressure differential
c) Venting procedure
This procedure allows the expulsion of air present in the
hydraulic circuit.
After manual selection of the "AIR" mode, the pump will
automatically alternate between maximum and minimum speed
for 10 minutes.
At the end of the procedure, the circulator will go to the pre-set
speed. You can then select the desired mode of operation
