Installation; Power Supply; Pairing Indoor Unit / Outdoor Unit - Alecto WS-4900 Mode D'emploi

3. INSTALLATION

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
battery.

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: HX075-0500600-AG-001. 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.
Outdoor unit:
Open the battery compartment by loosening the battery cover using a small
crosshead screwdriver. Insert 3 x 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°C, 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°C to 60°C. 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
Use a coin to unscrew the battery cover
for the backup battery by turning it an-
ti-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.
