BROAN-NuTone DD500W Digital Dehumidistat

The BROAN-NuTone DD500W Digital Dehumidistat is a robust solution for precise humidity management in residential and light commercial applications. This unit serves as a direct replacement for the DH100W, offering enhanced functionality and reliability. Designed to integrate seamlessly with existing ventilation systems, the DD500W transforms any standard exhaust fan into a responsive humidity sensing wall control. Operating at 120V, 60Hz, with a maximum load of 9 amps, it ensures compatibility with a wide range of Broan fans. Contractors will appreciate the user-adjustable rotary knob, allowing for a customizable humidity setpoint between 20% and 80% relative humidity. This precision control is crucial for mitigating moisture buildup, preventing mold and mildew, and ultimately improving indoor air quality. The unit features an optional "always on" mode for continuous ventilation and LED indicators to confirm fan operation, all within a standard single-gang box footprint.

Key Benefits for the Job Site:
