Leviton Mfg Co R02-DHS05-1LM Humidity Sensor Fan Control

Product Description

The LEVITON MFG CO R02-DHS05-1LM is a Decora-style humidity sensor and fan control switch designed for automatic exhaust and ventilation fan operation. The unit uses digital sensing technology to continuously monitor moisture levels and trigger a connected fan when humidity rises above a set threshold. It supports loads up to 300 watts for LED fixtures and 6 watts for incandescent or halogen sources. Licensed electricians and HVAC technicians install this device as a direct replacement for a standard single-pole switch, making it a straightforward upgrade in moisture-prone spaces.

This switch is suited for residential and light-commercial applications where humidity control is a priority. Typical install locations include bathrooms, basements, laundry rooms, and spas. The compact, shallow-profile design fits into standard wall boxes without modification. Sensitivity, target humidity level, and fan time-out duration are all field-adjustable, allowing the installer to tune the device to the specific environment. It is compatible with most bathroom exhaust fans and fan/light combination units.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. Shut off power at the circuit breaker and verify the circuit is de-energized with a non-contact voltage tester before beginning work. The device is wired as a line-voltage switch replacement; confirm load type and wattage do not exceed the rated limits before energizing. Do not install on circuits with motor loads exceeding the rated capacity of the device.
