I just installed the HSWF3 humidity control switch. The settings are still factory default. The switch keeps turning on. It will run for a minute and the start again. What is going on and how do I correct it?

Asked by: Paul485

The minus sign is low moisture sensitivity and the plus sign is high sensitivity; the dial can be set anywhere in between. In a very moist environment, lower sensitivity may be needed to avoid excessive fan run-time. In a very dry environment, higher sensitivity may be needed for the sensor to detect moisture. When DewStop senses condensation, the blue LED will pulse slowly. Setting Sensitivity: The factory setting of the moisture sensitivity dial is set to the noon position. If you feel the factory setting is too slow in turning on your fan, turn the dial to the right an hour at a time. Or, if you feel the factory setting turns your fan on too quickly, turn the dial to the left an hour at a time until the desired sensitivity level is reached.
