sensors
The remote weather sensors include a thermo-hygrometer (temperature and humidity) sensor, UV
(ultraviolet) 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 open area.
Remote UV sensor, anemometer and a rain gauge must be placed outdoors to measure
weather
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.

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 matching the polarity in the battery compartment
• Remove and discard any factory applied protective plastic film affixed to the 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).
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
Ideally they should be placed within the line of sight
°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.

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” size alkaline 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 into place by turning the
knobs clockwise.
Mounting
• Make sure that the rain gauge bucket is level – check for bubble center, inside built-in level.
• 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 freely away.

• Open the battery compartment and install 2 “AA” size alkaline 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 the button inside the “SET” opening located inside battery compartment with a paper clip
or similar tool. The “SET” selects a new direction for NORTH and, when pressed repeatedly,
alternates between the factory default NORTH and user selected NORTH.
• Select the factory set mode. It will be also a default setting in the future.
• Set current wind direction as NORTH.
Note: Repeat this procedure every time when changing the batteries.
Mounting
Mount the anemometer onto a vertical surface, using the fittings provided.
Placement tips:
• The anemometer should be mounted in an open area with a free air flow; away from the nearby
trees, buildings or other structures.
