INSTALLATION
The Weather Station portion of TN924W operates at 433MHz radio frequency, so no
wire installation is required between the main unit (receiver) and the remote weather
sensors (transmitters).
The remote weather sensors include a thermo-hygrometer (temperature and humidity)
sensor, anemometer (wind sensor) and a rain gauge (rain sensor). All data measured by
these remote sensors is transmitted to the main unit wirelessly, with the operating range
in the open area from 100 feet (30 meters) for anemometers and rain gauge up to 328
feet (100 meters) for temperature and humidity sensor.
Remote anemometer and a rain gauge must be placed outdoors to measure weather
elements.
Remote thermo-hygrometers can be placed indoors or outdoors, depending on the
area where the temperature and humidity are intended to be measured. If you intend
measuring outdoor temperature and humidity, place the remote sensor outdoors.
NOTE: It is critical to assemble and power up all of the remote weather sensors
BEFORE setting up the main unit.
NOTE: It is critical to power up and test communication between all of the weather
sensors and the main unit BEFORE permanently mounting them outside.
The Weather Radio segment of TN924W operates at frequency band from 162.400MHz
to 162.500MHz and requires AC adapter connected at all times.

BEFORE YOU BEGIN
• ALWAYS install batteries in the remote weather sensors before the main unit
• We recommend using alkaline batteries for the remote weather sensors and
the main unit when temperatures are above 32°F (0°C). We recommend using
lithium batteries for the remote weather sensors when temperatures are below
32°F (0°C)
• Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain
correct power requirements)
• Insert batteries before first use, matching the polarity in the battery
compartment
• Remove protective plastic screen from LCD display (if any)
• During an initial setup, place the remote weather sensors close to the main unit
• After reception is established (all of the remote readings will appear on the
main unit’s display), position the remote sensors and the main unit within the
effective transmission range: 328 feet (100 meters) for temperature/humidity
sensor(s) and 100 feet (30 meters for anemometer and rain gauge. Ideally they
should be placed within the line of sight of the main unit. See placement tips in
the user manual for each remote weather sensor
• Transmission/reception range may be affected by trees, metal structures and
electronic appliances, by the surrounding building materials and how the
receiver (main unit) and transmitters (weather sensors) are positioned
• The main unit must be placed indoors.
• Place the remote weather sensors so that they face the main unit (receiver),
minimizing obstructions such as doors, walls, and furniture.
Note: When the temperature falls below freezing, the batteries in the outdoor
remote weather sensors may have reduced voltage supply and a shorter effective
range. We recommend using lithium batteries at temperatures of 32°F (0°C) and
below.
IMPORTANT: Make sure that remote weather sensors are easily accessible for cleaning
and maintenance.
We recommend cleaning the remote weather sensors periodically, as the dirt and debris
may affect sensors accuracy.
