The 933 water level limiter is used to protect boilers in hot water heating systems against burning out due to a lack of water. Installation is mandatory for closed heating systems in accordance with DIN EN 12828 with a heating output of more than 300 kW. For boilers with a lower heating output, installation is mandatory if it cannot be ruled out that unauthorised heating may occur in the event of a lack of water. In addition, the water level limiter 933 can be used wherever water level-dependent electrical switching processes are to be triggered and a test option is required without lowering the water level.
The water level limiter 933 is designed as a device with magnetic transmission of the float movement to a microswitch and enables testing without lowering the water level. The electrical switching unit can be rotated through 360° and can be replaced without draining the system. The water level limiter 933.1 locks after switching off. Once the fault has been rectified, the system is switched on again using the release button on the water level limiter.
