WARNING: TO AVOID FIRE, SHOCK, OR DEATH, turn off power at circuit breaker or
fuse and test that the power is off before wiring!
1. Identify your wires (most common):
NOTE: A Neutral wire (if present) or a Ground wire is required for operation. If
the wiring in the wall box does not resemble this configuration,
consult an electrician.
2a. Wire (when Neutral is NOT present)
Working on one connection at a time, connect wires as shown below.
NOTE: This device is designed so that the Line and Load wires can be wired
interchangeably.

Location
Features
Leviton's Humidity Sensor and Fan Controller senses the humidity of your bathroom
and turns your bath fan ON when the humidity gets too high. This reduces
condensation in your bathroom and increases ventilation when used in other
household spaces.
• Compatible with Incandescent, LED, CFL and ELV/MLV loads when used with
combination fan and light fixtures.
• Sensitivity adjustment.
• Built-in countdown timer feature for manual operation.
• Automatic ventilation/air circulation mode for continuous operation, with hourly
preset time-outs.
• With Zero Cross turn-ON technology to extend the life of the switching relays.
• Advanced sensing enhances detection when room is occupied, and minimizes
false triggers when room is unoccupied.
• Color change kits are available in white, light almond, ivory, black, brown,
and gray.
• Also available as a Combination Single Pole Humidity Sensor and Fan Controller
with Light Switch (DHD05).
For bathroom applications, the device should be placed at a level that can detect
steam. Placing the detector directly above a heater or near drafts is
NOT recommended.
NOTES:
• The Humidity Sensor and Fan Control will not eliminate all condensation and
must be used with a properly sized ventilation fan in an enclosed space.
• DO NOT use to control a fan/light combination where the fan/light is the only
means of illumination.
