The current filling level is recorded in the primary tank by the "LIS" level sensor and evaluated in the controller. The value for the
minimum filling level is specified in the controller's Customer menu. If the level drops below the defined minimum, the "WV" make-up
valve opens and fills the primary tank.

-up function from the drinking water system, Reflex offers the Fillset with integrated system
separator and Fillsoft softening equipment,see chapter
