indicates main unit batteries are low.
NOTE
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.
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. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).
3. Select a channel. Make sure you use a different channel
for each sensor.
4. Place the sensor near the main unit. Press
RESET
on
the sensor.
5. Simultaneously press
CHANNEL
and
MEM
on the main
unit to initiate signal sending between the sensor and
main unit.

6. Close the battery door and secure the screws.
7. Place the sensor in the desired location using the table
stand or wall mount.
For best results:
•
Place the sensor out of direct sunlight and moisture.
•
Do not place the sensor more than 30 m (
100 ft
) 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
Data is sent from the sensor(s) every 40 seconds. The sensor
reception icon in the temperature and humidity area shows
the status.

CLOCK
CLOCK RECEPTION
This product is designed to synchronize its date and time
automatically once it is within range of the WWVB-60 signal
from the atomic clock in Boulder, Colorado.
The sensor collects the radio signals whenever it is within
1500 km (932 miles) of a signal.
NOTE
Initial reception takes 2-10 minutes for first set up or
when
RESET
is pressed. Once complete, the reception icon
will stop blinking. If the signal is weak, it can take up to 24
hours to get a valid signal.
