THE ELECTRONIC CIRCULATOR
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 fl ow.

WORK CONDITION
The pump works in base of its
settings
The pump works 10 minutes to
purge the air. After it is neces-
sary to set the power
The pump will start to work
automatically when the pro-
blem is solved
The pump is stopped (blocked) The pump doesn't start automa-
The pump doesn't receive the
voltage
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
