For double filter systems, alternating, including programmer

Commands the single effect membrane chamber with spring return. The pilot distributor has its own inner program (it does not need a controller or PLC).
Connecting for six membrane chamber, six programmable phase pilot (5 phase of the regeneration).

  • volumetric
  • temporized or
  • with external signal (analyzer, pressure switch)

With daily inner timer.

Output relais (n.o. / n.c.)

REL1: additional programme no. 1 (activation before, during or after regeneration –
duration programmable)
REL2: second additional program no. 2 programmable (as above)
REL3: general alarm or impulse dosage (only with water meter)
REL4: exercise valve filter 1 (add solenoid valve) or a contact during the supply of the treated water and a contact during regeneration
REL5: exercise valve filter 2 (as above)

Analogic output

4 – 20 mA: operation signal of the plant double filter and general alarm


WM: Pulse water meter
IN1: Stop remote regeneration (stop a regeneration into force)
IN2: Start regeneration or stop (block the start of a regeneration)
IN3: Opening/closing exercise remote valve
Examples of use: close the treated water supply in case of storage tank full
IN4: Hold regeneration
Examples of use: stop the regeneration where it is as long as the contact part (example: wash the softening as long as the conductivity of the discharge falls within the expected range, wash the filter as long as the turbidity falls within the expected value)
