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. As a backup, you may install
2x AA 1.5V penlight alkaline batteries. (excl.).
3.1 Power supply
Indoor unit:
The indoor unit is powered by the supplied power adaptor with model number XY06J- 0500150Q-EW.
Connect this power adaptor to the rear of the indoor unit (see 6) and insert the adaptor into a 230V wall
socket.
At the rear of the indoor unit, remove the battery cover and install 2x AA 1.5V penlight batteries according
to the markings inside the battery compartment. Replace the battery cover onto the indoor unit.
Outdoor unit:
Remove the battery cover from the outdoor unit by sliding it somewhat downwards and then taking it off.
Install 2x AA 1.5V penlight alkaline batteries according to the markings inside the battery compartment.
Replace the cover onto the outdoor unit and slide it somewhat upwards.
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 tempera-
ture 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 a signal from
the outdoor unit for 2 minutes. 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 can’t find each other or you’ve replaced the batteries in the indoor unit, you may link the out
-
door unit to the indoor unit as follows:
1. Press and hold the “-” button at the rear of the indoor unit for 2 seconds, the outdoor temperature and
humidity indicators now show ‘- -’. The indoor unit now waits for a signal from the outdoor unit for up to
2 minutes.
2. Within these 2 minutes, press the
TX
button on the outdoor unit (
see
the battery compartment of the
outdoor unit).
3. On the outdoor unit the red send light briefly illuminates and the outdoor unit transmits a signal to the
indoor unit, automatically pairing both units with each other.
In case the paring between the outdoor unit and indoor unit doesn’t succeed, it might be caused by
the distance between the indoor unit and outdoor unit being to long. In this case, decrease the
distance and try pairing again. Also interference from other cordless devices or large steel surfaces such
as walls of reinforced concrete may be the reason for a failed pairing. In this case, try a different location
for the outdoor or indoor unit.
