SYR Water Level Limiter 932.1, G 2

The water level limiter 932 serves to protect boilers in hot water heating systems against overheating due to lack of water. In closed heating systems according to DIN EN 12828 with a heating capacity of more than 300 kW, installation is mandatory. For boilers with a lower heating capacity, installation is mandatory if it cannot be ruled out that impermissible overheating may occur in the event of a lack of water. In addition, the water level limiter 932 can be used wherever water level-dependent electrical switching operations are to be triggered and a testing option without lowering the water level is required.
The water level limiter 932 is designed as a device with magnetic transmission of the float movement to a microswitch and allows testing without lowering the water level. The electrical switching unit can be rotated 360° and can be replaced without draining the system. The water level limiter 932.1 locks after shutdown. Once the fault has been rectified, the system is switched on again using the unlock button on the water level limiter. As a special version, model 932.5 with a shortened design is available.
