WARNING
Turn the POWER OFF at the circuit breaker before installing the sensor
Read and understand these instructions before installing. This device is
intended for installation in accordance with the National Electric Code and local
regulations. It is recommended that a qualified electrician perform
s
this
installation. Make sure to turn off the circuit breaker or fuse(s) and make sure
power is off before wiring the device.
Use copper wires only. NEUTRAL WIRE IS REQUIRED.
WIRING DIRECTIONS
As illustrated in Figure 1, The DWHOS has a 180° detection range with a
maximum distance of 24’ detection in front of the sensor
and
12
' on the sides
.
For maximum results, the sensor must be properly installed between the height
of 4’ to 5’ and away from obstructions such as walls, furniture and transparent
barriers like Low-E glass.

SPECIFICATIONS
DESCRIPTION
The DWHOS is a 3Amp, single pole Humidity/PIR occupancy sensor switch. This
Sensor helps conserve energy and automate the light and fan in which it is
connected. When the humidity sensor detects excess humidity in a room it
automatically turns on the ventilation fan. The sensor continues to monitor the air
and automatically turns the fan off when the humidity level drops below its preset
level. Combines both technologies to reduce energy usage by operating the light
or the fan only when needed.

NG INSTRUCTIONS
Single Pole
Wiring Diagram
The DWHOS features
two
adjustable operation modes for customized control to
suit the specific ventilation
and
light
ing
needs of the room. These modes are as
follows;
Occupancy with
Automatic Humidity
and Vacancy with Automatic
Humidity.
The count-down timer can also be adjusted to set the minimum "ON" time for the
lights at
10
minutes,
20
minutes, or 30 minutes.
The fan will automatically turn on
depend on the preset humidity.
Once the Timer has been set, the switch will
automatically turn the lights off when the selected time has expired. However the
fan will continue to operate if the sensor detects excess humidity.
The Fan will
Automatically turn off after the humidity level is reached.
The sensor switch is equipped with adjustable humidity level
s
. The humidity
sensor can be adjusted
to low
, medium, or
high
level.
When the PIR sensor detects movement the light button's green LED indicator will
be flashing. The fan's LED will turn red when the sensor detects excess humidity
in a room; otherwise, it will always stay lit in white.
Press and hold both light and fan buttons for 10 seconds, the green LED indicator
will come on solid. This setting allows users to switch back and forth between
Occupancy and Vacancy Mode.
•
Occupancy Mode*
- Auto On/Automatic Off Lights. Auto On/
Automatic Off Fan base on preset humidity level.
o
Light: Auto On, Auto Off.
The Light will automatically turn ON by
PIR sensor. Auto OFF by Time Delay.
When manual button is used to turn ON, lights turn ON and then turn
OFF by preset time delay.
When manual button is used to turn OFF before the preset timer
expired, lights turn off completely. After 3 minutes, PIR preset timer
will resets and lights turn ON if motion is detected.
o
Fan: Auto On, Auto Off.
The Fan will turn ON automatically when
preset humidity level is reached and automatically turn OFF when the
humidity level drops below the preset.
If the humidity level is higher than preset then the fan will continue to
run after a 5 minutes break.
When the manual button is used to turn ON, the fan will turn ON for
20 minutes and automatically turn OFF.
When the manual button is used to turn OFF before the 20 minutes,
the fan will turn OFF immediately and the humidity sensor will stop
detecting. Only when the manual button is used to turn ON again,
after 20 minutes the humidity sensor will be operational again.
•
Vacancy Mode
-
Manual On/Automatic Off Lights.
Auto On
/
Automatic Off Fan base on preset humidity level
o
Light: Manual On, Auto Off.
Manual button is used to turn the
Lights ON and Lights turn OFF automatically after preset time delay.
If motion is detected (within 30 seconds) of the lights turning off, the
Lights will remain ON
