Leviton DHS05-1LW

Model # R02-DHS05-1LM

Leviton's DHS05-1LW Decora Humidity Sensor Switch and Fan Control detects excess humidity in a room and automatically activates an exhaust or ventilation fan helping to reduce condensation and provide a more comfortable environment. The sensor uses state-of-the-art digital sensing technology to continuously monitor and manage moisture levels in areas of the home prone to humidity like bathrooms, basements, laundry rooms and spas. Replaces an existing switch and can be used with most bathroom or ventilation fans or fan/light combinations. Easy DIY install with slim depth for an easier fit in the wallbox, interchangeable line and load wires to help prevent miswiring, and a green flex sleeve that connects to ground or neutral when the sleeve is removed. User-friendly customization to adjust sensitivity, humidity level and time out settings and easy color change using the DHKIT faceplates available in white, ivory, light almond, gray, black and brown. Use with Decora Wallplate and Decora Plus Screwless Wallplate sold separately.

Operating Mode Descriptions

BATH FAN MODE
Operations	When/Where to use	Your fan will...
AUTOMATIC (Auto-ON/OFF)	For bathrooms and areas where significant changes in humidity can occur	Fan will turn ON when the humidity rises above the Sensitivity setting (Low, Medium, High, or Max.). The fan will stay ON for the Time Period you set. After the fan turns OFF, if the humidity is still above the threshold, it will retrigger and turn the fan ON for half the Time Period set (up to a maximum of 2 retriggers)
MANUAL (Pressing the button)	Any time you want to turn the fan ON/OFF.	Fan will turn ON and stay ON for the Time Period you set. Fan will turn OFF for a minimum of 2 minutes and then resume Auto-ON monitoring.
BYPASS (Hold BOTTOM of the button for 5 seconds)	To temporarily disable the Auto-ON functionality of sensor. To exit Bypass, press the TOP or BOTTOM of the button.	Fan will NOT turn ON automatically. The GREEN light will blink twice every 2 seconds.

AIR CYCLE MODE
Operations	When/Where to use	Your fan will...
AUTOMATIC	Basements, bathrooms, and rooms requiring regular ventilation (meets ASHRAE 62,2).	Run every hour, for the Time Period you set (X minutes). Ex: If the fan is set to be ON for 20 minutes, it will be OFF for 40 minutes (1 hour minus 20 minutes).
MANUAL (Pressing the button)	Any time you want to turn the fan ON/OFF.	If the user turns the fan ON manually, the device will act as if that was the start of a new hour-long cycle. If the user turns the fan OFF manually, the device will enter the OFF period for the remainder of the hour.
BYPASS (Hold BOTTOM of the button for 5 seconds)	To temporarily disable the air cycle. To exit Bypass, press the TOP or BOTTOM of the button.	Fan will NOT cycle air periodically. The GREEN light will blink twice every 2 seconds.

HUMIDISTAT MODE
Operations	When/Where to use	Your fan will...
AUTOMATIC (Air Cycle above RH set point)	Basements, laundry rooms, and damp rooms.	When the Relative Humidity (RH) is greater than or equal to the Humidistat setting (35%, 50%, 65%, or 80%), the fan will run for the Time Period you set (X minutes). When the Time Period expires, the fan will turn OFF for the remainder of the hour. NOTE: Fan will run for X minutes every hour, until the RH is less than the humidistat setting.
MANUAL (Pressing the button)	Any time you want to turn the fan ON/OFF.	If the user turns the fan ON manually, the device will act as if that was the start of a new hour-long cycle. If the user turns the fan OFF manually, the device will enter the OFF period for the remainder of the hour
BYPASS (Hold BOTTOM of the button for 5 seconds)	To temporarily disable the Humidistat functionality of the sensor. To exit Bypass, press the TOP or BOTTOM of the button.	Fan will NOT turn ON automatically. The GREEN light will blink twice every 2 seconds.

Test Mode

To test that your device is working properly, hold the TOP of the button down for 5 seconds. A RED light will blink once every 2 seconds. You are now in Test Mode.
Blow humid air into the sensor. During Test Mode, an increase in humidity will trigger the load for 5 seconds. NOTE: If the device does not trigger, then the room may be too large or the device may be too far away from a source of humidity.
Exit Test Mode by pressing either the TOP or BOTTOM of the button. The Test Mode will also time-out after 2 minutes.

What to do if...

If the humidity sensor false triggers, reduce the Sensitivity to a lower level.
If the sensor does not trigger or it turns the fan ON late, increase the Sensitivity level.
If the fan turns OFF too soon, increase the time in the Time Period setting
