7.4 Switching and make-up variants
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 equipmen

7.4.1.1 Using a single-tank system
1 Heat generator
3 Primary vessel
4 Control unit
5 Reflex Fillset
ST Dirt trap
WC Make-up pipe
PIS Pressure transducer
WV Make-up solenoid valve
EC Degassing line
• For gas-rich water from the system.
• For degassed water into the system.
LIS Level sensor
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
2035.
If you cannot achieve this quality, use the Reflex Fillsoft to soften
the make-up water from the mains water network.

LIS Level sensor
District heating water is particularly suitable as make-up water.
• Water treatment is not necessary.
• Use an "ST" dirt trap with a mesh size ≥ 0.25 mm for the make-up.
Note!
You require the approval of the district heating water supplier.
