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.
Note!
To complete the make-up function from the drinking water system, Reflex offers the Fillset with integrated system
separator and Fillsoft softening equipment,see chapter 4.6 "Optional equipment and accessories" on page 13 .
