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.

synchronise with remote sensor, reset both the main
unit and sensor or try selecting a different channel, then
reinstall the batteries and press TEST.
The remote sensor reception icons will show the following
status:
ICONS MEANING
Main unit is searching
for sensor(s), time
interval (4 minutes)
A sensor has been

(normal working model)
and “--.-“No sensor found
Place the remote sensor within 100 m (328 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:

• 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.
