SPRING – Wireless weather station
7.3.2 Trend pointers
• The trend arrows indicate whether the values for temperature and humidity are currently
increasing, steady or decreasing.

7.4 Weather forecast symbols

• There are 6 different weather symbols (sunny, slightly cloudy, cloudy, rainy, stormy and snow-
fall).
• The weather forecast relates to a range of 12 hours and indicates only a general weather trend.
For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean
the product is faulty because it is not raining. It simply means that the air pressure has dropped
and the weather is expected to get worse but not necessarily rainy.
• The sun symbol also appears at night if there is a starry night.
Important note!
• Please note that the forecast symbol will become more defined in the course of operation. The
forecast symbol is active right from the start, however, the reliability of the forecasts increases
with the amount of data collected. To begin with, the sensor must adapt initially to the refer-
ence level at the site. The forecast symbol will become at its most reliable after about 30 days.
7.5 Setting of the outdoor temperature and indoor temperature alarm
• Press the ALERTS button in normal mode.
• HIGH and 60 °C (default) or the last adjusted upper temperature limit appear on the display.

(Measuring range: 0°C...+50°C / +32°F...+122°F)
7.5.1 Activate and deactivate the outdoor and indoor temperature alarm
• To activate or deactivate the respective alarm functions, press the ALERTS button in normal
mode.
• HIGH and the last adjusted upper temperature limit is indicated.
• Press the ▲ button to activate the alarm function.
• Press the ▼ button to deactivate the alarm function.

7.5.2 Case of alarm
• In the case of an alarm the corresponding symbol will be flashing and an alarm sound is activated.

7.6 Display of the dew point
• Press the HEAT/DEW button, to show the current dewpoint temperature.
• On the display appears DEW-POINT and the temperature.
• The display automatically switches back to the current display of temperature and humidity.
• This interdependency of temperature and relative humidity is expressed by means of the dew-
point: If the air is cooled continuously at constant absolute humidity, then the relative humidi-
ty will steadily increase up to a maximum of 100%. If the air is cooled further, then the excess
water vapour is separated out in the form of water droplets.
8. Positioning and fixing of the basic station and the outdoor transmitter
• With the foldable leg at the back of the basic station, the basic station can be placed onto any
flat surface.

SPRING – Wireless weather station
• With the hanging holes at the back of the basic station, the basic station can be wall mounted
at the respective location. Avoid the vicinity of any interfering field like computer monitors or
TV sets and solid metal objects.
• The outdoor transmitter can be placed onto any flat surface or wall mounted at the respective
location by the hanging hole at the back of the unit. Choose a shady and dry position for the
transmitter. (Direct sunshine falsifies the measurement and continuous humidity strains the elec-
tronic components needlessly).
• Check the transmission of the signal from the outdoor transmitter to the basic station (transmis-
sion range of up to 60 m free field). Within ferro-concrete rooms (basements, superstructures),
the received signal is naturally weakened.
• If necessary choose another position for the outdoor transmitter and/or basic station.
9. Care and maintenance
• Clean the instruments with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries and pull out the plug of the socket, if you do not use the products for a
long period of time.
• Keep the instruments in a dry place.

9.1 Battery replacement

• Change the batteries of the outdoor transmitter when the battery symbol appears on the dis-
play of the outdoor values.
• Change the batteries of the basic station when the battery symbol appears on the display of the
indoor values.
• Please note: When the batteries are changed, the contact between outdoor transmitter and
basic station must be restored – so always insert new batteries into both units or start a manual
outdoor transmitter search.
