SYR Water Level Limiter 932.5, G 2

The 932 water level limiter is used to protect hot water heating systems from burnout due to lack of water. Installation is mandatory for closed heating systems according to DIN EN 12828 with a heating output of more than 300 kW. For boilers with lower heating output, installation is mandatory if it cannot be ensured that impermissible overheating may occur in the event of a lack of water. In addition, the 932 water level limiter 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 932 water level limiter 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 by 360° and can be replaced without draining the system. The 932 water level limiter locks after switching off. 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 has a shortened design compared to model 932.1.
