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
we

ather 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 thermo­hygrometers 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
re

quirements).

• 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 se

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

E

: 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

MOUNTING

• The remote thermo-hygrometer sensor can be placed on the flat surface or mounted on the wall in
vertical position.

• Use the wall mount hardware and screws provided when mounting the thermo-hygrometer sensor
on the wall.

PLACEMENT TIPS:

• The remote thermo-hygrometer sensor should be placed in the area with a free air circulation and
sheltered from the direct sunlight and an extreme weather conditions.

• Ideally, place the thermo-hygrometer sensor above the natural surfaces (such as a grassy lawn).

• Avoid placing the thermo-hygrometer sensor near sources of heat such as chimneys and heating

elements.

• Avoid any areas collecting and r

MOUNTING

• Make sure that the rain gauge bucket is level – check if the ball bearing inside the bucket is at the
midpoint of the leveler.

• Place the protective screen over the top to protect the rain gauge from the debris.

• Mount the rain gauge in place using mounting hardware provided.

• Make sure that the rain gauge is in open area where precipitation falls directly into the gauge’s

bucket, idea

PLACEMENT TIPS

• The rain gauge should be placed in an open area away from walls, fences, trees and other
coverings, which may reduce the amount of rain collected in the bucket. Additionally, trees and
rooftops may be sources of pollen, leaves and other debris.

• To avoid rain shadow effects, place the rain gauge two to four times the height of any nearby

ASSEMBLY

• With a flashlight, look into the mounting hole that will receive the anemometer axle shaft, on the
back of the wind cups. Check that the set screw is backed off appropriately, not obstructing the
opening.

• Place the wind cups over the axle shaft protruding from the anemometer housing and gently slide
into place.

• Insert the Allen wrench tool provided into the wind cups opening and tighten t

ide.

ins

he small set screw

• Test to assure the wind cups are securely mounted on the anemometer shaft and spin freely

BATTERY INSTALLATION

• Remove four (4) screws from the battery compartment with a small Phillips screwdriver.

• Open the battery compartment and install 2 “AA” batteries (not included) matching the polarities

shown.

• Replace the battery compartment door and secure the screws.

ALIGNING

• Point the wind direction vane to the North (use a compass or map if necessary).

• Press “SET” opening located inside battery compartment with a paper clip or similar tool. This will

“SET” the local wind direction to North. Continued pressing of “SET” alternately toggles wind
direction between the factory default preset or user set direction.

NOTE

: Repeat this procedure every time after whenever changing the batteries.

MOUNTING

Securely mount the anemometer base to an appropriate vertical surface, using the fittings provided.

PLACEMENT TIPS:

• The anemometer should be mounted in an open area with unobstructed air flow; away from the
nearby trees, buildings or other structures.

• Aim for a maximum exposure of the anemometer to the most common wind directions in the area.

•

The suggested mounting height for the anemometer is 33 feet (10meters) above the ground.

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
fo

r 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:

5

• 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.

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

rature alert function is available for each channel. It can be programmed to sound if the

A tempe
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
temperature reaches the alert temperature, it will have to fall below the alert temperature plus
the deviation (0.5°C) to activate the alert.

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 cor
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 t

•

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.
