This continuously monitors the relative humidity (RH) of the extracted air and triggers Boost Speed when the relative humidity rises over the set threshold. The Humidity Sensor’s trigger point is variable from 55%RH to 85%RH and is configured using step-less independent potentiometer. If the firmware on the PCB is FW0020-0200, then This continuously monitors the relative humidity (RH) of the extracted air. -

o Change units speed to determine if difference is then audible. Unit speeds can be determined by looking at the top of the relevant potentiometer and seeing where the arrows point. If the arrows on the continuous and boost pots are in the same or similar positions the flow rates and noise will be similar. -
