DHOS
Dual Technology
Humidity/PIR Motion Sensor
♦ SPECIFICATIONS
Minimun light load 10W or two light bulbs

The OHOS is a 3Amp, single pole Humidity/PIR occupancy sensing
switch.The OHOS help conserve energy and automate the lights in
your home. With it's humidity sensor and fan control automatically
detect excess humidity in a room such as bathrooms and basement
and responds by turning on the ventilation fan.The sensor continues to
monitor the air and automatically turns the fan off when the humidity
level has dropped below its preset level .Combines both technologies
can help reduce energy usage by operation the light or the fan only
when needed.
♦ COVERAGE
The coverage range of OHOS is illustrated and specified in Figure 1.
The diagram shows the motion detection area with small motion detection
closer to the sensor. Barriers within the space which blocks the line-of-sight
to the sensor detector will decrease the coverage area.
Best: 150 sq. ft.
Regular: 400 sq.ft.
Maximum: 600 sq.ft.

The switch has four adjustable functions. Each function is shown below
*Factory default setting is indicated with (*)
Note: when the PIR sensor is detecting movement the light green
LED indicator will start flashing. The fan's LED will turns red when
the sensor detect excess humidity in a room otherwise it will always
stay lit in white.
Function 1: Time delay for the light and the fan
1. 15 seconds(')
2. 5 minutes
3. 15 minutes
4. 30 minutes
Function 2: Three adjustable modes
1. Automatic Humidity : Light (manual on, auto off), fan (automatically on
depends on humidity level) (*).
2. Automatic On/Automatic Off with PIR: When motion is detected, both
the light and the fan turn on automatically and turn off based on occupancy
for the selected time delay and humidity level.
3. Manual On/Automatic Off: Both the light and the fan turn on manually
and turn off automatically based on occupancy for selected time dela:
and humidity level.
Function 3: Ambient light level
(to keep the light off if the ambient light is sufficient)
1. Disabled
2. 5 Foot-candle r)
3. 10 Foot-candle
4. 20 Foot-candle
