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.
THGR221
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.

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.
