PresSystem poate fi configurat sa functioneze ca
un presostat clasic. Pentru folosirea acestei
functii trebuie schimbat modul de operare
folosind instructiunile din sectiunea 5 (LED
ON/OFF).
Modul de operare ce trebuie selectat pentru
functionarea in regim de presostat este F6.
Cand dispozitivul este setat sa functioneze in
mod Presostat, porneste pompa cand presiunea
este mai mica decat presiunea minima de
repornire. Pompa este oprita cand presiunea
masurata in instalatie atinge presiunea maxima
setata.
Presiunea maxima are o setare implicita de 3 bar
si presiunea minima are setarea implicita de 2
bar. Valorile implicite pot fi modificate de catre
utilizator.
In modul de operare tip Presostat PresSystem
permite:
 Protectie contra Lipsa Apa prin controlul
amperajului (vers. cosφ) sau prin
configurarea presiunii minime de intrare in
protectia Lipsa Apa (LED DRY RUNNING)
la versiunea fara cosφ.
 Protectie supratensiune (vers. cosφ)
 Protectie impotriva resetarilor dese sau
pentru pierderi in vasul de expansiune (ex.
cand acesta este spart).
The PresSystem can be configured to work as a
pressure switch. To use this option you need to
change the operating mode by following the
instructions in paragraph 5 (LED ON/OFF).
The operation mode that should be selected is
the F6.
When the device is configured to operate from a
pressure switch, it activates the pump when the
pressure measured is lower than the restart
pressure. The pump is switched off when the
measured pressure reaches the maximum
pressure.
The maximum pressure has a default value of 3
bar and the restart pressure has a default value
of 2 bar.
The default values can be changed by the user.
In pressure switch operation the PresSystem
allows:
 protection against dry running by
controlling the power factor (cosφ version),
or configuring the dry running pressure
(without cosφ) (LED RUNNING DRY).
 Amperometric protection (vers. cosφ)
 Protection for frequent restarts or for
breaking expansion tank.
