Enerlites DWHOS-W Dual-Load Humidity and Motion Sensor Switch
The DWHOS-W is an Enerlites dual-load humidity sensor and 180° PIR motion sensor wall switch in white designed for intelligent bathroom ventilation and lighting control. Experience superior comfort and energy efficiency with dual-technology sensing that automatically manages both your exhaust fan and lights based on humidity levels and occupancy. This two-in-one control combines passive infrared motion detection with humidity sensing—ideal for bathrooms, laundry rooms, basements, and home spas requiring automated moisture management and hands-free lighting.
Enerlites DWHOS-W Features
- Dual-Technology Sensing: Combines passive infrared (PIR) motion detection with humidity sensing in a single device for complete bathroom automation
- 180° PIR Motion Sensor: Wide field of view provides up to 600 sq.ft. of coverage area for reliable occupancy detection
- Occupancy/Vacancy Modes: Two operating modes for lighting control—occupancy mode auto-on/auto-off, vacancy mode manual-on/auto-off
- Adjustable Lighting Time Delay: Customize light duration from 10, 20, or 30 minutes after motion stops
- Automatic Humidity Detection: Monitors moisture levels and activates exhaust fan when condensation is present
- Adjustable Fan Time Delay: Fan continues running for 20 minutes after humidity returns to normal for complete moisture removal
- Humidity Override Option: Manual control allows fan operation independent of humidity sensing when needed
- Dual-Load Capacity: Controls fan load up to 3A (1/4 HP) and lighting load up to 500W tungsten or 400VA/150W electronic ballast/LED
- Separate Light and Fan Loads Required: Independent control of lighting and ventilation circuits
- Interchangeable Face Cover: Customize appearance with alternative color face covers (sold separately)
- Single-Pole Configuration: Standard single-location wiring for straightforward installation
- White Finish: Clean white thermoplastic construction coordinates with standard wallplates
- Neutral Wire Required: Requires neutral connection for sensor operation
- UL Listed & California Title 24 Compliant: Meets safety standards and energy code requirements
Dual-Load Humidity and Motion Sensor Applications
- Residential bathrooms and powder rooms
- Master bathroom suites with showers and tubs
- Basement bathrooms and moisture-prone areas
- Laundry rooms and utility spaces
- Home spas and steam rooms
- Guest bathrooms and en-suite facilities
- Multi-family residential units
- Light commercial restrooms
Installation & Operation
The Enerlites DWHOS-W installs in a standard single-gang wallbox with neutral wire connection required for proper sensor operation. Separate wiring is needed for the light load and fan load—the device cannot control a single combined circuit. Configure the 180° PIR motion sensor to operate in occupancy mode (auto-on/auto-off) or vacancy mode (manual-on/auto-off), with adjustable time delays of 10, 20, or 30 minutes using front-accessible controls. The humidity sensor automatically activates the fan when moisture levels are high and continues running for 20 minutes after humidity normalizes. Use the humidity override for manual fan control when immediate ventilation is needed. The 180° field of view covers up to 600 sq.ft., and the interchangeable face cover allows color customization to match your décor.

Frequently Asked Questions
What does a humidity switch do?
What does a humidity switch do?
A humidity switch monitors the moisture level in the air and automatically turns on a ventilation fan when it detects high humidity, then turns it off once the air has cleared.
Where should I install a humidity sensor switch?
Where should I install a humidity sensor switch?
They are most effective in bathrooms, laundry rooms, home spas, and basements—anywhere prone to condensation, dampness, or mold growth.
Will the fan turn on every time it rains?
Will the fan turn on every time it rains?
Not if you have a high-quality humidity sensor switch. Modern sensors use "rate-of-rise" technology to distinguish between the fast moisture increase of a shower and the slow, natural increase of a rainy day.
Can I manually turn the fan on?
Can I manually turn the fan on?
Yes. Every humidity switch includes a manual override button. If you need immediate ventilation for odors, you can press the button to run the fan for a set "timeout" period.
How long does the fan stay on?
How long does the fan stay on?
This is determined by your "Time Delay" setting. Most switches allow you to choose between 10, 20, 30, or 45 minutes. The fan will run for this duration or until the humidity drops below your set threshold.
