6. Installation

Refer to the illustrations on page 2-3 of this manual.

6.1 Assembly

The thermo-hygrometer, rain collector, and wind direction sensor are already mounted on the shaft. You just need to attach the wind cups for the anemometer.

1. Push the wind cups onto the anemometer's steel shaft [K].
2. Use an Allen key (incl.) to tighten the screw on the side of the wind cups [L].
3. Spin the wind cups and make sure they can move freely. If the movement is hindered, the wind speed measurements will be incorrect.

6.2 Initialising the weather station

Before installing the weather station in its final location, you must install batteries in the outdoor unit and base station, and let the devices initialise and synchronise. This makes sure that the communication between outdoor unit and base station is working correctly. Poor communication can often be improved by changing the location.

Battery guidelines

Do not puncture batteries or throw them in fire as they may explode. Do not attempt to recharge nonrechargeable batteries (alkaline). Dispos of batteries in accordance with local regulations. Keep batteries away from children.

• Use only batteries of the correct size and voltage.
• Remove the batteries from the indoor and outdoor units if the device will not be used for a long time. Old batteries can begin to leak and damage the device.
• Respect the polarity when inserting batteries. The wrong polarity can damage the device.
• Alkaline batteries have a typical operating temperature range of -20^ +54^ . Do not use the device outside this temperature range.

Installing batteries in the outdoor unit

1. At the bottom side of the rain collector, loosen the screw and slide the metal catch sideways to free the battery compartment [G].
2. Pull out the battery compartment [H].
3. Insert 2 × AA 1.5 ~V LR6 batteries according to the polarity markings in the compartment [I].
4. Push the battery compartment back into the rain collector base [J].

The LED located at the back of the rain collector lights during 4 seconds. If not, check if the batteries are inserted properly.

1. Slide the metal catch back in position to secure the battery compartment, and fasten the catch with the screw.

Installing batteries in the base station

1. Open the battery compartment cover at the back of the base station.
2. Insert 3 × AA 1.5V LR6 batteries according to the polarity markings in the compartment.

All segments on the LCD display light up during 2 seconds. If not, check if the batteries are inserted properly.

1. Close the battery compartment cover.
2. At this moment, do not press any buttons yet.

Allow the device to initialise and synchronise with the outdoor unit first.

If necessary, remove the batteries from the indoor unit and wait for at least 10 seconds before you put them back in.

1. Wait until both indoor and outdoor temperatures appear on the display before you continue.

The transmitter sends weather data to the base station every 48 seconds.

Radio-controlled clock signal reception

After inserting batteries, the transmitter in the outdoor unit sends weather data to the base station, and then scans for the DCF radio-controlled clock (RCC) signal to set the date and time automatically. When the DCF signal is detected, the LED at the back of the rain collector flashes 5 times, then lights during 20 seconds. The

transmitter sends the date and time information to the base station. The display will show the RCC icon

If the DCF signal is poor and reception is not possible, the transmitter stops searching after 1 minute, and returns to normal operating mode (= transmitting weather data to the base station). The transmitter retries once every two hours to receive the DCF signal. If it cannot find the DCF signal, or if the last signal was

received more than 12 hours ago, the RCC icon will disappear from the display.

Note: The best time for DCF signal reception is at night between midnight and 6:00am, when there is less atmospheric interference.

During DCF signal reception, the transmitter does not send weather data to the base station. DCF signal reception lasts max. 5 minutes.

Note: if it is not possible to receive the DCF signal, you can set the date and time manually. See 7.2 Units, date and time. However, when the transmitter receives the DCF signal, it will overwrite your manual date and time settings.

6.3 Installation

Note: Assemble the weather station and make sure that the communication between outdoor unit and base station is working correctly before you install the weather station into its final location. Problems with radio transmission can usually be solved by changing the location.

When choosing a suitable location for outdoor unit and base station, take the following into account:

• Radio communication between transmitter and base station can reach up to 100m (330ft) in the open field, provided that there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines...
• Radio interference from PC screens, radios, or TV sets can disturb or even entirely cut off radio communication.
  Shelters such as trees, hedges, walls... can influence the measurements. Choose an open area where the elements can reach the sensors from all sides.
  For accurate wind speed measurements, keep the device away from buildings, trees, or other obstructions.
• For accurate temperature measurements, keep the device away from heat sources such as buildings, the ground, and direct sunlight without proper shielding in hot weather environments.
• For accurate humidity measurements, keep the device away from the ground, grass, or other sources of humidity.

Install the weather station as follows:

1. Make sure the outdoor unit is fully assembled and batteries are installed in outdoor unit and base station.
2. Place the outdoor unit and base station in the locations where you want them, and check if the communication is working.

If yes, continue with the next step.

If no, change the location of the outdoor unit and/or base station until proper communication is established.

1. Use the adjustable hoops (incl.) to attach the shaft of the outdoor unit to a mast [M]. Before you tighten the screws, check if the weather station is positioned well, as described below.
2. On the edge of the wind direction sensor, there are markers [N] representing the north (N), east (E), south (S), and west (W). Use a compass (not incl.) to position the device so that the markers correspond with your real location: the N marker must be directed north, the E marker east... If you do not position the sensor correctly, the wind direction measurement will be incorrect.
3. Use the bubble level [B] on the rain collector to position the device perfectly level.
4. Fix the device in its final position by tightening the screws on the adjustable hoops [M].

10. Calibration

For accurate measurements, you can calibrate wind speed, temperature, humidity, and rainfall measurements using calibration tools (not incl.).

To enter calibration mode, proceed as follows:

1. From normal mode, press and hold HISTORY for 8 seconds.
   The station is now in calibration mode. The wind factor digits on the display flash.
2. Press SET to go to the next setting; use the + or MIN/MAX keys to change the values.
3. To exit the calibration mode, press HISTORY.

See below for a description of each calibration setting.

Wind speed calibration

The default wind speed calibration setting is 1.0. The adjustment factor ranges from 0.75 to 1.25. You can set it in 0.01 increments.

Wind speed is the most sensitive to installation constraints. The following factors influence wind speed measurement:

the location of the weather station: proximity of buildings, trees, or other obstructions
- the wear of the moving parts of the anemometer.

To calibrate the wind speed, we recommend using a calibrated wind meter (not incl.) and a constant-speed, high-speed fan (not incl.).

Temperature calibration

You can calibrate indoor and outdoor temperature measurements.

The following factors influence temperature measurement:

• proximity of heat sources, such as buildings, the ground...
• installation in direct sunlight without proper shielding in hot weather environments.

To calibrate the temperature, we recommend using a mercury or alcohol thermometer (not incl.). Do not use bi-metal (dial) or other digital thermometers, as they have their own error margin. Do not use a local weather station in your area (difference in location, timing of updates, and possible calibration errors).

To calibrate the temperature, proceed as follows:

1. Place the temperature sensor in a shaded, controlled environment.

2. Place the thermometer right next to it.

3. Allow the installation to stabilise for 48 hours.

4. Compare the temperature reading on the display to the temperature reading on the thermometer, and adjust the setting in calibration mode to match the thermometer.

Humidity calibration

The hygrometer sensor's accuracy is ± 5% . You can improve the accuracy by calibrating indoor and outdoor humidity measurements.

Humidity measurements can drift over time. The proximity of humidity sources such as the ground, grass... influence the measurement.

We recommend using a sling psychrometer (not incl.) or commercially available humidity calibration kits (not incl.) to measure humidity. Adjust the setting in calibration mode to match the measurement.

Rainfall calibration

The default rainfall calibration setting is 1.0. The adjustment factor ranges from 0.75 to 1.25.

We recommend using a tube type rain gauge (not incl.), with an aperture of at least 10cm ( 4'' ). Any smaller and the readings may not be accurate. Do not use rainfall readings from weather reports on radio, TV, newspapers, or even your neighbour's weather station (difference in location).

To calibrate the rainfall measurement, proceed as follows:

1. Place the tube rain gauge right next to the rain collector of the weather station.
2. Compare the totals of three storms.
3. Based on this, develop an average for how far off the readings are.

Total rainfall calibration

To calibrate the total rainfall value, keep in mind that the factor is applied to the running total, not to individual tips of the bucket in the rain collector.

You can adjust the total rainfall in 0.3mm steps.

The total rainfall measurement works as follows:

1. The rain collector is calibrated at the factory so that the bucket tips over (and records rainfall) for every 0.3mm (0.01^ ) of rain.
2. The total number of times the bucket tips over (since the last reset) is counted and multiplied by 0.3 to get a total in mm. (For a reading in inches, a conversion factor is applied.)
3. The calibration factor is then applied to this total.

11. Cleaning and maintenance

11.1 Replacing batteries

Replacing batteries in the base station

When the display becomes difficult to read, replace the batteries. See Installing batteries in the base station.

Caution: When you remove the batteries from the base station, you lose all previous weather data and alarm settings.

Replacing batteries in the outdoor unit

When the battery level in the transmitter is low, the display will show that case, replace the transmitter batteries as soon as possible. See Installing batteries in the outdoor unit.

Note: Take into account that the low battery indicator only works correctly within an outdoor temperature range of 10 35^ . Outside this temperature range, the low battery indicator may show even if the batteries are still good.

When you replace the batteries in the transmitter, the transmitter will resynchronize with the indoor station within the next 3 hours. All previous weather data and alarm value settings are maintained.

However, if you want the devices to synchronise faster, you can remove the batteries from the indoor station and replace them after 10 seconds.

Caution: In this case you lose all previous weather data and alarm settings.

11.2 Replacing the sensors
