INTRODUCTION
The PMWS2W 110 degrees Surface Mount 2-Wire
Wall Switch is a fully automatic indoor controller
capable of controlling up to 2000W incandescent
lightings. It has been specifically designed to replace
manually operated light-switches in so called 2-wire
installation. It adopts 16A bistable relay of which
nature is high switching power and longer expected life
for electrical and uses a passive infrared (PIR) motion
sensor which reacts to changes in temperature
emitted by the motion of persons or objects passing
through its detecting area. When you enter the room,
it turns on automatically the light to which it is
connected and the light remains lit as long as the wall
switch senses any activity in the room. It however will
automatically turn off the light after the preset turn-off
time is expired. During the day, the built-in photocell
sensor saves electricity by deactivating the light.
When turning to AUTO position, the sensor will draw
power from the battery and constantly monitor the
battery voltage; whereas it is also a must to connect to
AC mains supply, providing power source to
connected light fixture when motion has been detected.
Please take note that it is an automatic light switch
which cannot be used in intrusion applications.
It is a very handy device, which affords you safety,
security, convenience and energy saving. It is also
easy to install and is suitable for the following places:
living room, family room, stairway, entryway, garage
and driveway etc.
With this wall switch installed, you get rid of the
nuisance of fumbling in a dark hallway or staircase for
a light switch, thus avoiding danger for the elderly,
infirm and children at night or when it is dark.
Note: Read this entire manual before you start to
install the system.

Be sure to switch off power source before
installing.
Make sure that the power wiring comes from
circuit with an external miniature circuit breaker
not higher than 16A for the short circuit protection
or a suitable fuse.
The unit cannot be installed on the ceiling.

IMPORTANT
Installation must be performed by a skilled/competent
person who is familiar with the appropriate standards
and technical requirements of the appliance and its
proper installation.
Before proceeding with the installation, TURN OFF
THE POWER TO THE LIGHTING CIRCUIT AT THE
CIRCUIT BREAKER OR FUSE BOX TO AVOID
ELECTRICAL SHOCK.

For the best results, fix your sensor on a solid
surface, at least 1.7m above the ground.
For indoor installation, a location under eaves is
preferable.
Avoid aiming the motion sensor at pools, heating
vents, air conditioners or objects which may
change temperature rapidly.
Do not allow sunlight to fall directly on the front of
unit.
Try to avoid pointing the unit at trees or shrubs or
where the motion of pets may be detected.
The motion sensor is more sensitive to objects
moving across its field of view. It is less
sensitive to an object moving directly towards the
sensor head. (FIGURE 2)
