WMS 2-1 / WMS 3-1

Variants Documents

  • for protection of the boiler when the water level is too low
  • electronic version with visual alarm and power outage lock
  • TÜV-tested as a water level switch
  • Direct mounting via welding socket

For sealed heating systems to protect the boiler as per EN 12828 and VdTÜV sheet "Water Level 100" (edition 07, 2006) in the case of low water levels.

This self-monitoring electronic boiler water low level alarm with integrated power outage lock operates on the basis of the conductivity principle (resonant circuit). Consisting of control unit in wall mounting housing with test and unlock buttons, visual alarm, angled probe with welding sockets, electrode and electrode test facility. TÜV-tested as a water level switch.
If the water level in the boiler drops below a minimum level, the electrode is no longer submerged. The electronic system de-energises a relay which switches off the power supply for the burner and activates the alarm lamp. The electrical locking mechanism keeps the burner from switching back on automatically. The test button allows you to simulate a low water alarm condition.
Version WMS 3-1 for external power outage lock.
