INSTALLATION

General’s Wireless Data Logging Weather Station 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 (2) thermo-hygrometer (temperature and humidity) sensors,
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. If you intend measuring outdoor
temperature and humidity, place the remote sensor outdoors, preferably not in the direct sunlight.

BEFORE YOU BEGIN

The components of this complete Wireless Weather Station operate wirelessly at 433MHz radio
frequency.
No interconnecting wires are required between the main unit (receiver) and the remote sensors
(transmitters). Power up and test communications between all of the sensors and the main unit
BEFORE mounting them outside.

• For most applications alkaline batteries are acceptable where temperatures remain above 32°F
(0°C).

• Avoid using rechargeable batteries. (Rechargeable batteries do not provide correct power levels).

• ALWAYS install batteries in the remote sensors before the main unit.

• Insert batteries matching the polarity in the battery compartment.

• Remove plastic sleeve from LCD display (if any).

• During an initial setup, place the main unit close to the remote 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 sensor.

• 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 (sensors) are positioned.

• Place the remote sensors so that they face the main unit (receiver), minimizing obstructions such as
doors, walls, and furniture.

• Make sure that the remote sensors are easily accessible for cleaning and maintenance.

NOTE

: When the temperature falls below freezing, the outdoor sensor batteries may have reduced

voltage and a reduced effective range. We recommend using lithium batteries at temperatures
below 32°F (0°C).

IMPORTANT: We recommend cleaning the remote sensors periodically, as dirt and debris affects sensor
accuracy.

BATTERY INSTALLATION

• Remove the screws from the battery compartment with a small Phillips screwdriver.

• Set the channel 1 through 3. The switch is located in the battery compartment. Set one sensor to
Channel 1 and the second sensor to Channel 2, etc. The sensors must operate on
separatechannels.

• Install 2 “AA” batteries matching the polarities shown in the battery compartment.

• Replace the battery compartment door and secure the screws.

• Secure the thermo-hygrometer remote sensor in the desired location.

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 areas that collect or radiate heat from the sun, such as metal, brick/concrete structures,
paving,
or patio decks.

• The best location for temperature measurements is 4 feet (1.25meters) above the ground.

and rainfall counting
electronics.

E. BATTERY COMPARTMENT

Holds two “AA” batteries.

F. SCREWS

Secures battery compartment
cover.

G. BUILT-IN LEVEL WITH BUBBLE

Ensures level rain gauge
mounting for proper operation.

H. BUCKET SEE-SAW MECHANISM

I. PROTECTIVE SCREEN

Protects the rain gauge funnel from debris.

BATTERY INSTALLATION

• Unlock the funnel-shaped top on the rain gauge by turning both knobs on the sides in an anti­clockwise direction.

• Remove the funnel-shaped top lifting it off the rain gauge bucket.

• Remove 7 small screws from the battery compartment cover using a small Phillips screwdriver.

• Insert 2 “AA” batteries (not included), matching the polarities as shown in the battery
compartment.

• Replace the battery compartment door and secure the screws.

• Insert the funnel-shaped top into the rain gauge bucket and secure it in place by turning the knobs
clockwise.

MOUNTING

• Make sure that the rain gauge bucket is level – check inside built-in level for bubble center.

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

• Where practical, mount the rain gauge in place with wood screws (not included).

• Make sure that the rain gauge is in open area where precipitation falls directly into the gauge’s
bucket,
ideally 2-3 feet above the ground.

PLACEMENT TIPS

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

• To avoid the rain shadow effects, place the rain gauge horizontally, on the distance corresponding
to two to four times the height of any nearby obstruction.

• It is important to locate the unit where rain can flow away freely.
