WEATHER TENDENCY DISPLAY

The weather station indicates the weather tendency with a graphic symbol in the

upper left of the display. The calculation is done in the same way as for the weather

forecast, by observing the change of atmospheric pressure. Pay attention to the

information in the chapter “Weather forecast”.

Weather improvement (rising atmospheric pressure)

No weather change (constant atmospheric pressure)

Weather deterioration (falling atmospheric pressure)

BAR GRAPH DISPLAY FOR CHANGE OF ATMOSPHERIC

PRESSURE

The course of the atmospheric pressure of the last 12 hours is shown in the right of

the display with a bar graph.



At start-up (or after replacing the batteries), measured data are not available

and all bars have the same height.

ATMOSPHERIC PRESSURE

The atmospheric pressure measured by the integrated pressure gauge is shown in

the top right of the display (pressure unit “hPA”).

The weather station displays the actual atmospheric pressure, which is dependent

on the altitude of your home (the higher this place the lower the atmospheric pres-

sure).



Please note that the atmospheric pressure values you might ﬁ nd e.g. on the

internet are always converted in relation to sea level. Thus, a deviation of

the reading of the weather station is the result.

DISPLAY OF MOON PHASE

In the upper right of the display you ﬁ nd the moon phase. It is calculated automati-

cally based on the date (either via DCF signal or via the manually set date).

COMFORT INDICATOR

Above the depiction of the weather forecast, you can ﬁ nd the comfort indicator

which provides with all current environmental conditions around the location of the

weather station:

too dry (humidity < 40%)

ideal (temperature 20 - 28 °C, humidity 40 - 70%)

too damp (humidity > 70%)



If nothing is displayed, the temperature at the location is < 20 °C or > 28 °C.

CLEANING AND MAINTENANCE

The product is maintenance-free for you; you should never dismantle it (except for

inserting/replacing the batteries as described in these operating instructions).

To clean the exterior of the weather station, a dry, soft and clean cloth is sufﬁ cient.

Do not press too hard on the display of the weather station, this may cause scratch-

es or the display to malfunction; furthermore, the display might break.

Dust on the weather station can be easily removed with the help of a long-haired,

soft and clean brush and a vacuum cleaner.

Use a slightly damp soft cloth to remove dirt from the outdoor sensor.

Do not use aggressive cleaning agents or cleaning alcohol as it can impair the func-

tion.

DISPOSAL

a) Product

Dispose of an unserviceable product in accordance with the relevant statu-

tory regulations.

b) Batteries and Rechargeable Batteries

As the end user, you are required by law (Battery Ordinance) to return all used bat-

teries/rechargeable batteries; disposal of them in the household waste is prohibited!

Contaminated batteries/rechargeable batteries are labelled with these sym-

bols to indicate that disposal in the domestic waste is forbidden. The sym-

bols for the relevant heavy metals are: Cd=Cadmium, Hg=Mercury, Pb=Lead

(marked on batteries/rechargeable batteries, e.g. under the rubbish bin

symbol shown to the left).

You can dispose of your used batteries/rechargeable batteries free of charge at your

community’s collection point or any place where batteries/rechargeable batteries

are sold!

You thereby fulﬁ l your statutory obligations and contribute to the protection of the

environment.

RANGE

The transmission range of the radio signals between outdoor sensor and weather

station is up to 30 m under optimum conditions.



This range speciﬁ cations refer to the so-called „free-ﬁ eld range.“

However, this ideal arrangement (e.g. weather station and outdoor sensor on a plain,

even meadow without trees, houses etc.) never exists in practice.

Usually, the weather station is placed inside a house and the outside sensor is placed

e.g. under a carport or at a window.

Due to the different inﬂ uences on the radio transmission, no speciﬁ c range can be

guaranteed.

However, trouble-free operation is usually possible in a detached house. When the

weather station doesn’t receive any data from the outdoor sensor (despite new bat-

teries), reduce the distance between outdoor sensor and weather station, change

the installation site.

The range can sometimes be limited considerably by:

Walls, concrete ceilings

Coated/vapour-deposited insulating glass panes, aluminium windows

Vehicles

Trees, bushes, earth, rocks

Proximity to metallic & conductive objects (e.g. heating elements)

Proximity to human bodies

Broadband interferences, e.g. in residential areas (DECT telephones, mobile

phones, radio-controlled headphones, radio-controlled speakers, other radio-con-

trolled weather stations, babyphones etc.)

Proximity to electric motors, transformers, power supply units, computers

Proximity to mains sockets, network cables

Proximity to improperly shielded or uncovered operating computers or other elec-

trical devices
