NOTE Install batteries in the remote sensor before the
main unit. Press RESET after each battery change. Do
not use rechargeable batteries. We recommend that
you use alkaline batteries with this product for longer
usage and lithium batteries in temperatures below
freezing.

UNIT LOCATION
Main Indoor temperature area
Remote Outdoor temperature area
REMOTE SENSOR
The sensor collects temperature readings approx.
every 40 seconds and sends them to the main unit. The
main unit can collect data from up to 3 sensors.
To set up the sensor:
1. Slide open the battery door.
2. Insert the batteries, matching the polarity (+ / -).
Press RESET after each battery change.
3. Select a channel. Make sure you use a different
channel for each sensor.
4. Close the battery compartment.
5. Secure the sensor in the desired location using the
wall mount or table stand.
For best results:
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 meters (100
feet) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor)
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 or electronic objects.
• Position the sensor close to the main unit during
cold winter months as below-freezing temperatures
may affect battery performance and signal
transmission.
The transmission range may vary depending on many
factors. You may need to experiment with various
locations to get the best results.
Standard Alkaline batteries contain significant
amounts of water. Because of this they will freeze
in low temperatures of approximately -12°C (10°F).
Disposable Lithium batteries have a much lower
threshold for temperature with an estimated freezing
range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold
may temporarily reduce the effective range between the
sensor and the base station. If the unit’s performance
fails due to low temperature, the unit will resume proper
functioning as the temperature rises to within the
normal temperature range (i.e. no permanent damage
will occur to the unit due to low temperatures).
SENSOR DATA TRANSMISSION
The reception icon in the outdoor temperature area
shows the status.
