Requires carpentry and electrical skills. Please note that this may need to be professionally installed. This unit has humidity-activated control, as well as movement sensors for the night light feature. That means the unit itself needs to have hot wiring 24/7 and not just when the wall switch is "on." Please read the wiring instructions FULLY as the switch wiring is different from other switches.
