b) Start-up of Other Sensors
If you want to use several additional temperature/air humidity sensors suited to the Weather Station
WS222, insert the batteries into the sensor(s) now. A maximum number of 8 of such sensors can
be operated.
The installation, addressing and start-up of the sensor is to be performed according to their operating
instructions.
c) Start-up of the Base Station
The base station is designed to indicate all registered and calculated data on a clearly arranged LC
display. The sensors for indoor use (temperature, air humidity, air pressure) are also included in the
housing of the base station.
For this reason, ensure during the start-up or installation of the base station that a heating or
ventilation system (e.g. an air-conditioning system) is not in its proximity, because false data could
be indicated in such a case. Avoid direct sunlight, too!
Keep to the following order of steps during the start-up:
• Open the battery compartment on the back side of the base station (remove the foot first, if
necessary!).
• Insert four batteries (AA/Mignon) in the battery compart-
ment paying attention to the correct polarity. You will find
the corresponding image in the battery compartment
(see also figure 4 on the right).
If possible use alkaline batteries.
As already described in chapter 6, accumula-
tors can be used, too. They, however, can have
a negative influence on the operating life, cov-
erage and operational safety.
• Close the battery compartment again.
• If the batteries are inserted, all segments of the LC
display will be shown briefly.
• Afterwards, the base station activates the synchronisation mode for 15 minutes. In this period of
time all sensors received will be indicated one after the other.
If all your installed sensors have already been received, you can cause a premature exit
of the synchronisation mode by pressing any button, provided that all sensors have
already completed their own synchronisation mode.
If you face any problem in the identification of one sensor, you should wait as long as the
synchronisation time is finished. This process takes 15 minutes.
