For single filter plants, within programmer
It controls the membrane chambers single effect with spring return. The pilot distributor has its inner programmer (it does not need a programmer or PLC).
Connection for six membrane chamber, six programmable phases pilot (5 phases of the regeneration).
Functioning:
volumetric
temporized or
with external signal (analyzer, pressure switch)
With daily inner clock
REL1: additional programme (activation before, during or after regeneration – programmable duration)
REL2: second additional programmable programme (as above)
REL3: general alarm
REL4: dosing pulse (only with a connected water meter)
REL5: exercise valve (add a solenoid valve) or a contact during treated water’s supply and a contact during regeneration.
