Airflow QuietAir QT150HT Fan With Adjustable Humidity & Timer

This QuietAir Humidity/Timer Fan carries the Quiet Mark Approval and is part of an extended range of elegant, discreet axial fans that are extremely quiet with various control options that activate the fan only when needed – the choices are: remote switching, timer, humidity with timer and motion sensor with timer.
This Humidity/Timer model has two ways of activating, it is activated by a rise in the level of humidity and it can be connected to a switch, it can be connected to the same switch as the light circuit or it can have its own switch. There is also the option to use both of the QuietAir speeds, a separate three way position switch should be used to achieve this, see our product code 9041315 Model 3POSSW.
When installing this fan you need to select which of the two speeds you want it to operate at if not using the three way switch above. This fan has various settings; these are adjustable by way of the dip switches located under the cover. The adjustable settings are: delayed timer on/off, the delayed timer function, you select the amount of run on time after switching the fan off, adjust the level of humidity that activates the fan and you can also turn off the humidity function. It comes factory set and you only need to access the dip switches if you want to change the factory settings. More detail is available in the wiring instructions included in the box.
