The Airflow iCON PRHTS is a versatile plug-in module designed for 12V low voltage iCON 15S and 30S extractor fans. It combines motion sensor activation, an adjustable humidity setting (40–90% RH), and a run-on timer (1–30 minutes) to provide intelligent, automatic ventilation control. Ideal for bathrooms and wet areas, the module activates the fan when movement or excess humidity is detected, then continues running for a set time to ensure optimal air quality. Easy to install and swap without replacing the fan, the PRHTS module is compatible with any SELV iCON fan and is backed by a 3-year warranty.
