Hot water / steam faucet
The hot water / steam valve has 3 positions:
1. Middle position = closed
2. Hot water / steam
3. Milk Island (not with Odea)
The three hot water / steam valve positions
are monitored using three Hall sensors and a
magnet that is fi tted to the hot water / steam
valve axle.

Pipe system pressure reduction:
The electrical valve opens to reduce the

Overpressure valve (safety valve):
As the multi-way valve already opens at 3 - 5
bar in the fl ow direction, it takes over the
overpressure function (1) when the brewing
unit is not in the brewing position. If the
brewing unit is positioned in the brewing
position in an overpressure situation and/or
the multi-way valve is blocked, the magnet
valve acts as an overpressure valve and opens
mechanically against the spring pressure at
16 - 19 bar (2).
