Variomat Touch — 09.2020 - Rev. A
The "LIS" level sensor uses a pressure load cell. This pressure pick-up is to be
installed after the primary vessel has been placed at its final position, see
chapter 7.3.3 "Tank installation" on page 10 . Comply with the following
instructions:
• Remove the transport securing device (squared timber) at the vessel base
of the primary vessel.
• Replace this transport securing device with the pressure load cell.
– In the case of a vessel volume of 1000 l (Ø 1000 mm) or more, use
the supplied screws to attach the pressure load cell at the vessel
base of the primary vessel.
• Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
• Use flexible hoses to connect the primary vessel and the first secondary
vessel.
– Use only the supplied connection sets, see chapter 7.3.3 "Tank
installation" on page 10 .
• Perform a null balancing of the filling level when the primary vessel is
aligned and fully emptied, see chapter 8.6 "Parametrising the controller in
the Customer menu" on page 17 .

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 equipment, see chapter 4.6 "Optional equipment and
accessories" on page 5 .

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.
– If you cannot achieve this quality, use the Reflex Fillsoft to soften
the make-up water from the mains water network.
