The rain detector WS-890 is designed for connection to SHE and ventilation control panels of SIMON PROtec Systems GmbH. The detector prevents excessive rain, leaving the windows controlled by the control panel open. A heated sensor surface avoids false triggering by snow, ice or dew. The period of time to respond to the rain can be adjusted thanks to the built-in time delay.
