Installing your weather station

Setting up the Remote Weather Sensors

Before starting up the main console unit, setup all the remote sensors first.

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 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 2 x "AA" size 1.5V batteries.
4. Use a pin to press the "RESET" key which is in the battery compartment of thermo-hygrometer sensors.
5. Replace the latch and mount unit at desired location.

Placement tips:

• The thermo-hygrometer 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 fittings 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 2 x "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.

1. 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.
2. 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, deflect 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 flow 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 2 x 1.5 V AA batteries (optional, not included) into the battery compartment in the base, observing the correct polarity. The anemometer is solar-powered. The batteries will operate as a backup power source.
4. Insert the adapter into the jack. The rechargeable battery is already installed and now ready to use.
5. Mount the anemometer onto a vertical surface, using the fittings provided. To allow the main console unit to indicate the correct wind direction, the wind vane must be oriented towards the north, while the wind vane is in line with the anemometer's arm. Use a compass if necessary.

Note: If the wind sensor cannot be fixed with the anemometer's arm towards the north, as provided by the default setting, you have to adjust the anemometer manually:

i. Insert the backup batteries (where required) and plug the adapter into the jack.
ii. Point the wind vane towards the north. Use a compass if necessary.
iii. Use a pin to press the "SET" key which is in the battery compartment of the wind sensor.

Above procedure must be repeated for changing battery.

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 flow and will attenuate readings.
• Aim for maximum exposure of the anemometer to the commonest wind directions in your area.
• The official 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 "AA" size 1.5V batteries according to the polarities shown.
3. Reattach the latch.
4. You are highly recommended to connect the AC/DC adaptor. For the feature of the 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 fitting provided.

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 finish self-calibration and for the sensor readings to show up.

Maintenance

Changing Batteries

The battery statuses of the sensors are checked every hour. If the low battery indicators light up, replace the batteries for the corresponding unit immediately.

Low batteries should be changed soon to avoid the damage resulting from a leaking battery. Batteries contain harmful acids. Wear protective glasses and gloves when handling with leaked batteries.

Attention: Please do not dispose of old electronic devices and used batteries in household waste. To protect the environment, take them to your retail store or to appropriate collection sites according to national or local regulations.

Changing Batteries for the Main Console Unit

1. To avoid losing data and records, connect the AC/DC adaptor to the main unit first.

2. Remove the latch at the back and replace all batteries. Do not mix old and new batteries.

3. Replace the cover.

Changing Batteries for the Remote Sensors

1. Replace the batteries following the setup instructions for the corresponding sensor.

2. When the batteries are properly installed, the sensor will resume sending signals to the main console unit.

To enforce a search immediately for all remote signals, press and hold the button [▼] on the main console unit.

Cleaning

The main console unit and outer casings for the remote sensors can be cleaned with a damp cloth. Small parts can be cleaned with a cotton tip or pipe-cleaner.

Never use any abrasive cleaning agents and solvents. Do not immerse any units with electronic parts in water or under running water.

Anemometer

- Check that the wind vane and wind cups can spin freely and are free from dirt, debris or spider webs.

Rain Sensor

Like all rain gauges, the rain sensor is prone to blockages due to its funnel shape. Checking and cleaning the rain sensor from time to time will maintain the accuracy of rain measurements.

• Detach the protective screen and lid. Remove any dirt, leaves or debris by cleaning the items with soapy water and a damp cloth. Clean small holes and parts with a cotton tips or pipe-cleaner.
• Look out for spiders or insects that might have crawled into the funnel.
• Also clean the swinging mechanism with a damp cloth.

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

Anemometer (Wind Sensor) - 15 minutes

Rain Sensor - 30 minutes

Check or replace the batteries for the corresponding sensor. Then press and hold the button [▼] 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.
• 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 official 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 reflect current weather conditions.
