INSTALLATION
Our Omega’s Full Weather Station #WS821 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 up to 328 feet (100 meters) in the open area. The
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 location where the temperature and
humidity are to be measured. If you intend measuring outdoor temperature and humidity, place the
remote sensor outdoors, preferably not in the direct sunlight.
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.
BEFORE YOU BEGIN
•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).
•ALWAYS install batteries in the remote weather sensors before the main unit.
•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 main unit close to the remote weather sensors.
•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 of up to 328
feet (100 meters). 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 separately.
•Transmission range may be affected by trees, metal structures and electronic appliances.
•The main unit must be placed indoors.
•The effective operating range may be influenced by the surrounding building materials and how the
receiver (main unit) and transmitters (weather sensors) are positioned.
•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 the 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.

ATOMIC TIME RECEPTION
The main unit synchronizes the time and date with WWVB radio clock broadcasts maintaining the
atomic time precision.
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology) radio station (WWVB) is located in Ft. Collins,
Colorado. It transmits an exact time signal continuously throughout the most of the continental United
States at 60 KHz frequency. The Atomic Time Clock in your weather station can receive this WWVB
signal through the internal antenna from up to 2,000 miles away. Due to the nature of the Earths
ionosphere, reception can be limited during the daylight hours. The radio controlled clock will search
for an alternate station that receives the atomic time signal from the NIST Atomic clock in Boulder,
Colorado.
The WWVB tower icon on the unit’s display will flash indicating a radio signal reception from the WWVB
station. If the tower icon is not fully lit, or if the time and date are not set automatically, please consider
the following:
FIRSTNEWLASTFULL
5

6
•During night-time hours, atmospheric disturbances are typically less severe and radio signal
reception may improve. A single daily reception is sufficient enough to keep the clock accuracy
within 1 second.
•Make sure the unit is positioned at 8 feet (2 meters) distance from any interference source such
as a TV, computer monitor, microwave, etc.
•Within concrete wall rooms such as basements or office buildings, the received signal may be
weakened. Always place the Projection Clock near the window for better reception.
Once the atomic time signal is received, the date and time will be set automatically, and the icon
will appear.
After the clock is set manually, place the main unit by the window for the better reception. The atomic
clock receiver is programmed that it will continue to search for the atomic time signal daily for every
hour between 1:00 am and 4:30 am.
Once the time signal has been successfully received, the time and date will be updated automatically.
To enable or disable the atomic time receiver:
•Press and hold UP - if atomic time reception is activated, a triangular tower icon will start
flashing next to the clock icon. If reception is disabled, the triangular tower icon will disappear.

TEMPERATURE AND HUMIDITY MODE
The weather station supports up to 3 remote thermo hygrometers corresponding to a separate channel
of the temperature and relative humidity display. The temperature can be displayed in Celsius (ºC) or
Fahrenheit (ºF).
The main unit carries the temperature and humidity sensor and uses this indoors data to calculate an
indoors comfort level - Wet, Comfort or Dry.
A temperature alert function is available for each channel. It can be programmed to sound if the
channel temperature exceeds or falls below the pre-set upper and lower limit.
NOTE:The temperature alerts have a 0.5 ºC deviation to prevent them from sounding due to small
temperature fluctuations that are close to the set alert value. This means that after the

TROUBLESHOOTING
Q: “The display shows dashes “---” for weather parameter(s)”
A: The display will show “- - -” when the wireless connection with the remote sensor is lost for the
following periods:
Thermo-Hygrometer: 15 minutes
UV Sensor: 30 minutes
Anemometer (Wind Sensor): 15 minutes
Rain Gauge (Rain Sensor): 30 minutes
Check or replace the batteries for the corresponding sensor. Then press and hold DOWN on the main
unit or handheld remote to enforce a search for all remote signals.
If this does not work, check the wireless transmission path from the corresponding weather sensor to
the main unit and change their locations if necessary.
Although wireless signals can pass through solid objects and walls, the weather sensor should ideally
be within the line of sight of the main unit.
The following may be the cause of reception problems:
•The remote weather sensor and a main unit are too far from each other.
•The signal shielding materials, such as metal surfaces, concrete walls or dense vegetation, are
in the path of transmission.
•There is interference from the wireless devices (such as cordless phones, radio headsets and
baby listening devices) and electronic appliances.
Q: “The weather readings on my weather station are different from the TV, radio or official weather
reports.”
A: The weather data may vary considerably due to different environmental conditions and placement
of the weather sensors.
Check the placement tips included in this manual to site your weather sensors in the best possible way.
Q: “The weather forecast is inaccurate.”
A: The weather forecast predicts the weather for the next 12 to 24 hours, and does not reflect
current weather conditions.
