Installing your weather station
Setting up the Remote Weather Sensors
Before starting up the main console unit, setup all the remote sensors rst.
When placing the sensors, make sure that they are within receiving range of the console
unit. Ideally they should be within the line of sight of the console unit. Transmission range
may be affected by trees, metal structures and electronic appliances. Test reception before
permanently mounting your weather station.
Also make sure that the sensors are easily accessible for cleaning and maintenance.
The remote sensors should be cleaned on a weekly basis, since dirt and debris will affect
sensor accuracy.
Setting up the UV Sensor
1. Unscrew the lid on top of the UV sensor.
2. Insert two 2 x UM-3 or “AA” size 1.5V batteries and screw the lid back onto the sensor
3. There are three different ttings available for mounting the UV sensor.
-Ground Stand:
Attach the circular ground stand onto the U-shaped sensor holder with the screws
provided.
-Stake:
Attach the sharp stake end onto the metal bar with the screws provided.
Attach the other end of the metal bar to the U-shaped sensor holder with the screws
provided.
-Wall mount:
Attach the wall mounting end onto the metal bar with the screws provided.
Attach the other end of the metal bar to the U-shaped sensor holder with the screws
provided.
4. Attach or place the sensor in a location with abundant sun exposure throughout the day.
6
Placement tips:
- The sensor should be mounted in an area free of shadows or reections of sunlight by
nearby coverings and objects.
Setting up the Thermo-Hygro Sensor(s)
1. Open the latch at the base of the thermo-hygro sensor.
2. Set the channel with a slide switch.
3. Insert two 2 x UM-3 or “AA” size 1.5V batteries.
4. Use a pin to press the “RESET” key which is in the battery compartment of thermo-hygro
sensors.
5. Replace the latch and mount unit at desired location.
Placement tips:
- The thermo-hygro sensor should be in an area with free air circulation and sheltered
from direct sunlight and other extreme weather conditions. Place the unit in a shaded
area, such as under a roof.
- Use the wall mount and ttings provided if mounting the unit on a vertical surface.
- Avoid placing the sensor near sources of heat such as chimneys.
- Avoid any areas which collect and radiate heat in the sun, such as metal, brick or
concrete structures, paving, patios and decks.
- Ideally, place the sensor above natural surfaces such as a grassy lawn.
- The international standard height for measurements of air temperature is at 1.25m (4 ft)
above ground level.
Setting up the Rain Sensor
1. Unlock the funnel-shaped top of the rain sensor by turning both knobs on the sides of
the rain sensor in an anti-clockwise direction.
2. Lift the top off the base and insert two 2 x UM-3 or “AA” size 1.5V batteries into the
battery holder.
3. Replace the lid and secure into place by turning the knobs clockwise.
4. Place the rain sensor in a location such that precipitation can fall directly into the sensor,
ideally 2-3 ft above the ground.
It may be secured into place by using the four screws provided.
5. The sensor must be accurately level for optimum performance. To check if the sensor
is level, remove the lid and check if the ball bearing inside is at the midpoint of the
leveler. Additionally, a bubble level or carpenter’s level may be used.
6. Attach the protective screen onto the top of the lid. The screen will prevent any debris
entering the sensor.
Placement tips:
- The rain sensor should be placed in an open area away from walls, fences, trees and
other coverings which may either reduce the amount of rainfall into the sensor, deect
the entry of wind-blown rain, or create extra precipitation runoff. Trees and rooftops may
also be sources of pollen and debris.
- To avoid rain shadow effects, place the sensor at a horizontal distance corresponding to
two to four times the height of any nearby obstruction.
- It is important that rain excess can ow freely away from the sensor. Make sure that
water does not collect at the base of the unit.
- The rainfall measurement mechanism utilizes a magnet, hence do not place any
magnetic objects around the proximity of the sensor.

Setting up the Anemometer (wind sensor)
1. Assemble the wind cups and wind vane to the anemometer arm
2. Attach the assembled anemometer to the base.
3. Insert two 2 x UM-3 or “AA” size 1.5V batteries into the battery holder in the base.
4. Mount the anemometer onto a vertical surface, using the ttings provided.
5. To allow the main console unit to nd the direction which the wind vane is oriented, the
following procedures are required:
i. Insert the batteries
ii. Point the wind vane towards the north. Use a compass or map if necessary.
iii. Use a pin to press the “SET” key which is in the battery compartment of the wind
sensor.
Note: Above procedure must be repeated for changing battery.
The “SET” will toggle the direction between two mode:
1. Let the wind direction as manufacturer design. It will be as a default setting after
2. Set the current direction as NORTH.
Placement tips:
- Check that wind can travel freely around the anemometer and is not distorted by nearby
buildings, trees or other structures.
- For better results, place the anemometer at least 3m above local structures and
obstacles. The ground creates a frictional effect to wind ow and will attenuate readings.
- Aim for maximum exposure of the anemometer to the commonest wind directions in
your area.
- The ofcial mounting location for anemometers is 10m (33 ft) above ground level in a
clear unobstructed location.
Setting up the Main Console Unit
1. Open the latch at the back of the main console unit.
2. Insert 4 x UM-3 or “AA” size 1.5V batteries according to the polarities shown.

automatic backlight control function, the AC/DC adaptor must be used.
5. If placing the console unit on a table or horizontal surface, fold out the table stand and
adjust to the optimal viewing angle.
6. If mounting the console unit on a wall or vertical surface, fold the table stand back into
the unit and use the tting provided.
8
Placement tips:
Make sure that the console unit is within receiving range of all remote sensors. Ideally
sensors should be within the line of sight of the console unit. Transmission range may be
affected by trees, metal structures and electronic appliances. Test reception before
permanently mounting your weather station.
The console unit measures indoor temperature, humidity, pressure and receives signals
from all remote sensors and radio-clock broadcasts. Avoid placing the console unit in the
following areas:
- Direct sunlight and surfaces which radiate and emit heat.
- Near heating and ventilation devices, such as heating ducts or air conditioners.
- Areas with interference from wireless devices (such as cordless phones, radio headsets,
baby listening devices) and electronic appliances.
Starting up the Main Console Unit
Once the console unit is properly powered, the display will start showing some data and
weather parameters. Wait for a few minutes for the console to nish self-calibration and for
the sensor readings to show up.

Troubleshooting
The display shows dashes “---” for weather parameter(s)
The display will show “---” when the wireless link is lost with the remote sensor for the
following periods:
Thermo-hygro Sensor – 15 minutes
UV Sensor – 30 minutes
Anemometer (Wind Sensor) – 15 minutes
Rain Sensor – 30 minutes
Check or replace the batteries for the corresponding sensor. Then press and hold DOWN
to enforce a search for all remote signals.
If the above does not solve the problem, check the wireless transmission path from the
corresponding sensor to the main console unit and change their locations if necessary.
Although wireless signals can pass through solid objects and walls, the sensor should
ideally be within the line of sight of the console unit.
The following may be the cause of reception problems:
- Distance between remote sensor and main console unit too long. (Maximum
transmission distance in open area conditions is 100m)
- Signal shielding materials such as metal surfaces, concrete walls or dense vegetation in
the path of transmission.
- Interferences from wireless devices (such as cordless phones, radio headsets, baby
listening devices) and electronic appliances.
The weather readings do not correlate with measurements from TV, radio or ofcial
weather reports.
Weather data can vary considerably due to different environmental conditions and
placement of weather sensors.
Check the placement tips included in this manual to site your sensors in the best possible way.
The weather forecast is inaccurate.
The weather forecast is a prediction of weather after 12-24 hours, and may not reect
current weather conditions.
