Center S2 ==> Ground: 2 - 6V AC:
water level too low
steam heating must switch OFF
solenoid valve filling Y1 ON
Center S2 ==> Ground: 0V AC:
water level reached
steam heating can switch ON
solenoid valve filling Y1 switched OFF
The level electrode is equipped with two side elec-
trodes to ensure a safe water level recognition even
though the level electrode is scaled. These side
electrodes compensate the build up of scale (CM).
Permanent water level control;
Maximum continous steam time: 2 Minutes,
Property of connected water:
Conductivity must be above 50μS/cm;
Overfilling of the steam generator can be caused by a
connected water treatment system.
