Attention: after the installation, it may take several hours up to a day before the correct values are displayed.

Attention: the indoor unit is powered by the supplied power adaptor. For backup power, you may insert the included 3V CR-2032 button cell.

3.1 Power supply:

Indoor unit:

The indoor unit is powered by the supplied power adaptor with micro USB plug. The model number of this adaptor is: HX12-0500500-AG. Only use this adaptor. Insert the plug of this adaptor into the rear of the indoor unit according to the picture below and insert the adaptor into a 230V wall socket.

Use a coin to unscrew the battery cover for the backup battery by turning it anti-clockwise and insert a CR-2032 button cell battery (not

incl.) according to the markings inside the battery compartment (minus pole downwards). Replace the battery cover and lock it by using the coin and turning the battery cover a little clockwise. See also 'OPEN' and 'CLOSE' on the battery cover.

Outdoor unit:

Open the battery compartment by loosening the battery cover using a small crosshead screwdriver. Insert 3 × size AA 1.5V batteries according to the figure below, paying attention to the polarity (+ and -). Replace the cover (batteries are not included).

Advice regarding the batteries for the outdoor unit:

Because normal alkaline batteries do not perform or do not perform well at temperatures around or below 0^ , the use of standard alkaline batteries in the outdoor unit is not recommended. For the outdoor unit, we therefore recommend installing Lithium batteries that have been designed to function at a temperature range of -20^ to 60^ . These batteries are available through the service department of Alecto via internet www.alecto.info

The lifespan of Lithium batteries with a capacity of 2900mAh is well over a year.

3.2 Pairing indoor unit / outdoor unit:

Automatically:

As soon as the batteries are inserted into the indoor unit, the indoor unit starts searching for a signal from the outdoor unit for 1 minute. So, if you have installed batteries in the outdoor unit within that minute and these units 'find' each other, they will automatically connect with each other and the display of the indoor unit will show the temperature, humidity, rainfall amount, wind speed and the wind direction as the outdoor unit transmits this data.

Manually:

If the units cannot be paired automatically, or after replacing the batteries, you can pair the outdoor sensor (again) with the weather station unit as follows:

1. Briefly press the SENSOR button at the rear of the indoor unit, the antenna symbol in the display starts flashing
2. Briefly press the RESET button on the outdoor unit.
3. The units will have found each other (again) after several seconds

3.3 Positioning:

Indoor unit:

You may choose to suspend the weather station from a wall using a simple screw or to use it as a desk model using the supplied table stand. In any case, never place the weather station in direct sunlight or nest to a heat-radiating lamp or stove.

Outdoor unit:

You may choose to place the outdoor unit onto a flat surface (e.g. a fence or railing) or to mount it on a pole (excluded). In any case, make sure to position the unit at least 1.5 meters above the ground, standing freely in the rain and wind.

General installation and placement tips:

• First check whether the outdoor unit is within range of the indoor unit before permanently installing it. Maintain a distance of a maximum of 30 meters between the outdoor unit and indoor unit.
• Make sure the outdoor unit is placed at least 1.5 meters above the ground and that the unit is openly standing in the rain and wind.
• For the rain meter to work as accurately as possible, the outdoor unit must be as horizontal as possible. To do this, use the built-in spirit level on top of the outdoor unit.
• To be able to indicate from which direction the wind is coming from, the outdoor unit must be oriented towards the north. See the indication N on top of the outdoor unit for this. Use a precise compass (excluded) to properly orientate the unit.
• Ensure that the outdoor unit is hanging or standing freely. Particularly the wind speed meter and wind vane must hang in direct wind.
• Find a location where the chance of blowing leaves is minimal. Leaves blown into the rain collector can block the rain meter or influence the measurement results. In any case, we recommend that you place the outdoor unit in such a way that it is fairly easy to remove any blown leaves and replace the batteries in the outdoor unit.
• Of course, you may first keep the outdoor unit within reach for a week to test all its functions. Only permanently install the outdoor unit after everything is functioning properly.

3.4Clock:

Introduction

The WS-4900 is provided with a built-in DCF receiver which receives the DCF time signal from Frankfurt. This signal ensures that the clock shows the time very accurately, provided a strong enough signal is being received.

Automatic:

As soon as you install the batteries into the indoor unit, the clock starts searching for the DCF radio signal to set the correct time and date while the antenna symbol flashes. After several seconds or minutes the WS-4900 will start showing the correct time. In extreme cases, it can take over a day before the DCF time is shown.

while searching for the radio signal, you cannot continuously switch on the display lighting. However by pressing the ALARM/SNOOZE button, the display lighting will switch on but switches off again after 5 seconds. As soon as the clock has found the radio signal, or when stopping the search by briefly pressing the RCC button, the display lighting switches on continuously.

Manually:

If the clock cannot receive the radio signal or cannot receive it well enough, you can set the clock manually as follows:

1. Press and hold the button for 2 seconds, 12Hr or 24Hr will appear in the display

2. Use / to set the time format, then briefly press the button

3. Use / to set the hours and then briefly press the button

4. Use / to set the minutes and then briefly press the button

5. Use / to set the seconds to 0 (this allows you to have the clock run synchronously with your own clock) and then briefly press the button

6. Use / to set the year and then briefly press the button

7. Use / to set the month and then briefly press the button

8. Use / to set the date and then briefly press the button

9. Use / to set the difference in hours as compared to the DCF time. For use in the Benelux, select '0' and briefly press the button

10.Use / to set the language for displaying the days, you may choose from: EN (English), FR (French), DE (German), ES (Spanish) or IT (Italian), briefly press the button

1. Use / to determine whether the clock must automatically switch to daylight saving time (AUTO) or this must be done manually (OFF), briefly press the button

The clock is now set manually.

When the DCF receiver is enabled and a strong signal is being received, the receiver will overwrite the clock display.

To switch the DCF receiver on/off:

You may switch off the DCF receiver as follows to only display the time and date you've programmed yourself:

• to switch off: press and hold the RCC button at the rear of the weather station for 8 seconds until OFF illuminates and the antenna symbol disappears

You may switch the receiver back on as follows:

• to switch on: press and hold the RCC button at the rear of the weather station for 8 seconds until ON illuminates, the antenna symbol starts flashing and the display turns green.

The symbol in the upper part and in the middle of the display shows the status of the DCF clock: No symbol: the DCF receiver is switched off; the displayed time is determined by the internal clock of the weather station

■ flashing: the DCF receiver is switched on and is searching for the DCF signal; the displayed time is determined by the internal clock of the weather station

remains lit: the DCF receiver is switched on and is receiving the DCF signal; the displayed time and date are determined by the atomic DCF clock in Frankfurt
