7.4.1 Function
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.
 Note!
To complete the make-up function from the drinking water system,
Reflex offers the Fillset with integrated system separator and Fillsoft
softening equipment,  4.6 "Optional equipment and accessories",

Single boiler system ≤ 350 kW, water temperature < 100 °C.
• Connect the Reflex Fillset with integrated system separator upstream
when using mains water for make-up.
• If you don't connect a Reflex Fillset upstream, use an "ST" dirt trap with a
mesh size ≥ 0.25 mm for the make-up.

Note!
The quality of the make-up water must comply with the applicable
standards such as VDI 2035.
