SENSOR
This product can work with up to 3 sensors at any one time
to capture temperature and relative humidity readings in
various locations around the home.
A complete set of 3 sensors are provided in this package,
while replacement wireless remote sensors can be
purchased separately.
THGR122N
This sensor conveniently displays the temperature /
humidity which makes it especially suited for locations
where you would like to see this data at a glance without
having to refer each time to the main unit, such as
children’s room.

connect the unit to the power grid source via AC/DC
adapter.
• Make sure the adapter is not obstructed and is
easily accessible to the unit.
•The base station and adapter should not be exposed
to wet conditions. No objects filled with liquid, such
as vases, should be placed on the base station and
adapter.
• To completely disconnect from power, unplug adapter
from the mains.
SYNCHRONISING AND PLACING SENSORS

sensor reset within the last 30 minutes. If unit failed to
synchronise with remote sensor, reset both the main
unit and sensor or try selecting a different channel (and
press RESET).
The remote sensor reception icons will show the following
status:
ICONS MEANING
Main unit is searching
for sensor(s)
A sensor has been
found and logged on
and “--.-“No sensor found
Place the remote sensor within 30 m (98 ft) from the
main unit.
TIP
• When placing sensors, remember the intended
location for each sensor. Refer to channel switch
position (1, 2, 3) and match with channel icon
displayed directly above name tag.
• The transmission range may vary depending on
many factors. You may need to experiment with
various locations to get the best results.
For best results:
• Place the sensor out of direct sunlight and moisture.
• Position the sensor so that it faces the main unit,
minimizing obstructions such as doors, walls and
furniture.
• Place the sensor in a location with a clear view to
the sky, away from metallic / electronic objects.
