Humidity Sensor (40–90% RH) – Automatically activates the fan when humidity rises. Factory pre-set to approx. 70% RH. Adjust sensitivity using the supplied adjustment tool.
Pull Cord Activation with Timer Control – When installed in an iCON fan, the module allows manual activation via the integrated pull cord. Once triggered, the fan runs according to the adjustable timer settings (2–45 minutes). This module supports two activation methods: humidity sensing and pull cord activation.
Recommended Humidity Settings for UK Climate – UK indoor humidity often ranges between 70–90% RH. Setting the module to 40% RH may cause the fan to run continuously. If the fan takes too long to switch off, adjust the humidity setting closer to 70–90% RH for better performance.
