Nice switch I like that the switch controls both lights and the fan. The only drawback is the wiring instructions could be better.. Daniel. Val Caron, ON. Sun Mar 02 2025

I found these worked well. I didn't realize at first that the second multi-switch must the same model, not another model or a simple 3/4 way switch. I also found that the switch didn't work well w/o adjusting the time settings. The switch would either conflict or run into a race condition where both switched switched "off" at the same time and it sent both switches into a non-functioning mode - button didn't work at all. Resetting the switch (manually) or via a power-off, and power-on (breaker) appeared to reset the switches, and both would work once, and then go into a hung mode. Adjusting the timing of the switches via the documentation so that they were not using the default times from the factory, caused both switches to work great. I have not tried to connect the white wire to make the light work yet.. Sellers. United States. Mon Dec 14 2020

The Leviton Humidity Sensor and Fan Control automatically detects excess humidity in a room and activates the ventilation fan to lessen condensation which helps reduce mould and mildew. The sensor uses a microprocessor combined with state-of-the-art digital sensing technology to continuously monitor and manage humidity levels in areas of the home prone to condensation and mildew. It features user-friendly controls to adjust sensitivity, humidity level and time out settings. The sensor can replace a single pole switch and can be used with most bathroom or ventilation fans or fan/light combinations. It is designed to fit within a standard wallbox and requires a neutral wire for operation. Contemporary in design, the Humidity Sensor and Fan Control is the ideal solution for controlling ventilation in areas of high humidity, dampness or rooms prone to condensation and mildew such as: Bathrooms, Basements, Laundry Rooms and Home Spas. The sensor also helps reduce energy usage by automatically operating the fan only when needed to control excess humidity.
