3 GENERAL FEATURES

The SFE-EV controller is a Siata dedicated controller designed for softening application. It regroups the
following main programmable features:
 Regeneration mode: Time clock, volume (immediate or delayed), or external signal start, depends how
the controller is programmed
 Integrated brine valve
 Variable brining option
 Control a chlorine cell (only with chlorine cell control board version)
 Salt sensor control
 Salt alarm feature
 2 programable relay outputs (control solenoid etc)
 IP index 40
 50 or 60 Hz
 Varistor included, to protect against voltage surges
 Auto-reset feature: If the processor detects a fault in the control logic for any reason, an appropriate
circuit triggers a general reset of the controller, reloading the default programming values
SFE-EV is available in 2 versions: standard or chlorine cell control. Software is the same for both, so there
are no differences in programming. Hardware is different, the chlorine cell control version is equipped with 2
extra relays and specific transformer. SFE EV controller also features a diagnostic menu where you can consult
the service data of the installation. SFE EV controller offers 2 levels of programming, 1 simplified and designed
