Main unit is searching for
sensor(s)
A sensor channel has been
found and logged on
and “--.-”
No sensor found
4. Secure the sensor in the desired location using the
wall mount hole.
TIP Ideal placements for the sensor would be in any location
on the exterior of the home at a height of not more than
1.5 m (5 ft) and which can shield it from direct sunlight or wet
conditions for an accurate reading.
For best results:
• Place the sensor within 30m (100 ft) of the main unit.
• 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.

EN

• Position the sensor close to the main unit during cold
winter months as below-freezing temperatures may
affect battery performance and signal transmission.
TIP The transmission range may vary depending on many
factors. You may need to experiment with various locations
to get the best results.
NOTE Use alkaline batteries for longer usage and consumer
grade lithium batteries in temperatures below freezing.
TEMPERATURE AND HUMIDITY
