♦ OPERATION ♦ TROUBLESHOOTING
The OHOS features three user-friendly adjustable modes for customized The switch buttons are not functional
control to suit the specific ventilation/light needs of the room.These modes Check if the device is installed and wired properly. The device requires
are follow; Automatic humidity, Automatic ON/OFF PIR , and Manual a neural wire for operation.
On/Automatic Off. Beside these three modes, the time control can be
adjusted to set the minimum on time of the lights and fan for 15 seconds.
5 minutes, 15 minutes, and 30 minutes. In order to save energy this
switch will automatically turns the lights off when its preset on time is
expired. However the fan will continue to operate if sensor detect excess
humidity and automatically turns the fan off when the humidity level has
dropped. The sensor switch is also equipped with adjustable ambient
light level and humidity level. The humidity sensitivity adjustment can
be adjusted from high, medium or low.
Automatic Humidity: Light (Manual On/Automatic Off),
Fan (Automatic On/Automatic Off)
The device is pre-set at the factory and required to turn on the light
manually and turn on the fan automatically when the excess humidity is
detected. The sensor keeps the light on when there is occupancy and
automatically turn off if no movement is detected and the time delay setting
has expired. While the fan will turn off after the humidity level dropped
under the humidityset level. If the humiditylevelof an enclosedspace is still
over the preset humidity level after 30 minutes running, the fan will
continue to run after 20 minutes break.
Automatic On/Automatic Off with PIR:
The light and fan will turn on automatically with PIR motion detection
and turn off automatically based on occupancy and humidity level
respectively. During the light/fan on state, the light will turn off
automatically if no movement is detected and the time delay setting has
expired. However the fan will continue to operate if sensor detect
excess humidity and automatically turns the fan off after 3 minutes when
the humidity level has dropped.
Manual On/Automatic Off:
The light and the fan will turns on manually and turn off automatically
based on occupancy and humidity level respectively. During the light/
fan on state, the light will turn off automatically if no movement is
detected and the time delay setting has expired. However the fan will
continue to operate if sensor detect excess humidity and automatically
turns the fan off after 3 minutes when the humidity level has dropped.
Manual On/Manual Off:
At any time the light and the fan can be manually controlled with the
push buttons on the switch.

Press the light or fan button
If the load does not work and the indicator light does
not flash
Turn OFF power to the circuit then check wire connections. Confirm
the neutral wire is connected, Black and Blue lead connect to Hot/Line
wire.
If the load operates normally, but the load will not
turn off.
Change sensor's mode of operation to desired setting and set to higher
humidity level.
Note: Do not use the switch to control a fan/light
combination where this is the only means of
illumination or light installed. The device will not
eliminate condensation solely and must be used with
a properly sized ventilation fan in an enclosed space.
