Leviton IPHS5-1LW Humidity Sensor and Fan Control, Single Pole, White

Automatically detects excess humidity in a room and activates the ventilation fan to lessen condensation which helps reduce mold and mildew, Sensor uses microprocessor and digital sensing technology to continuously monitor and manage humidity levels in a room.
Built-in timer sets the “minimum ON time” for the ventilation fan. The sensor time settings can be custom set to 10, 20, 30 or 45 minute intervals. The sensor will continue to operate the fan for the minimum time set or until there is a reduction in room humidity level.
A sensitivity level adjustment allows users to adjust the sensor’s sensitivity to ambient air to prevent false cycling.
Features an Air Cycle mode which automatically turns ON the ventilation fan for a set period of time and repeats the cycle hourly (eg. 20 minutes ON/40 minutes OFF each hour).
Replaces a single pole switch for control of ventilation fan or a fan/light combination, Fits in a standard wall box and requires a neutral for operation, The device’s built-in humidistat control meets CALGREEN requirements for Indoor Air Quality and Exhaust, Five-Year Limited warranty.
Automatically detects excess humidity in a room and activates the ventilation fan to lessen condensation which helps reduce mold and mildew.
