Sooo great!! Love the fan so much I bought another !

You need this for the fan system!

The sensor is iffy, you can adjust but it has a mind of its own. The controls for the lights are more complex than needed.

This control was purchased after seeing it was recommended for the bathroom light and fan we previously bought. Love the multiple features, especially the automatic humidity sensor.

This is a must if you bought the "90 CFM, 1.5 Sones Exhaust Fan for Bathroom Lighting Energy Star Certified Ceiling Ventilation" otherwise I think is an overkill for other units. the wiring is not easy but if you have time, and a decent electrical knowledge, you can figure it out.
