PRIMAVERA - Wireless weather station
10.2 Setting of the temperature unit
• In the normal mode you can change between °C (Celsius) or °F (Fahrenheit) as tem-
perature unit.
• Press the -/°C/°F button.
10.3 Heat index
• The heat index is the temperature perception in conjunction with humidity.
• Press the HEAT/DEW button in normal mode, to show the current heat index temperature.
• HEATINDEX and the temperature appear on the display.
• The indoor and outdoor humidity values disappear.
• The display automatically switches back to the current display of temperature and
humidity.

10.4 Dew point

• The 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 humid-
ity 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.
• Press the HEAT/DEW button, to show the current dew point.
• DEWPOINT and the temperature appear on the display.
• The indoor and outdoor humidity values disappear.
• The display automatically switches back to the current display of temperature and
humidity.
11. Additional outdoor transmitters
• For having more than one additional outdoor transmitter select with the 1/2/3 switch in
the battery compartment of the outdoor transmitter for each single outdoor transmitter
a different channel. The reception of the new transmitter will be transmitted automati-
cally to the base station. Press and hold the CH button on the base station or restart
the base station according to the manual.
• The outdoor values will be shown on the display of the base station. If you have
installed more than one outdoor transmitter, press the CH button on the base station to
change between the channels 1 to 3.
• You can also choose an alternating channel display. After the third channel, press the
CH button again, AUTO appears for an alternating channel.
• Press the CH button again to deactivate the alternating channel and the first outdoor
transmitter will be shown permanently.
• Once registered outdoor transmitters (channels), which are no longer needed, can be
deleted manually by pressing the CH button for three seconds. Once a new outdoor
transmitter is received, there will be another indicator.
12. Positioning and fixing of base station and the outdoor transmitter
• With the foldable leg at the back of the base station, the base station can be placed
onto any flat surface or wall mounted at the respective location by the hanging holes at
the back of the unit. Avoid the vicinity of any interfering field like computer monitors or
TV sets and solid metal objects.

PRIMAVERA - Wireless weather station
• With the hanging hole at the back of the outdoor transmitter, the transmitter can be
wall mounted at the respective location. Choose a shady and dry position for the out-
door transmitter. (Direct sunshine falsifies the measurement and continuous humidity
strains the electronic components needlessly).
• Check the transmission of the signal from the outdoor transmitter to the base station
(transmission 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 receiver.
13. Care and maintenance
• Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries and pull out the power adapter of the socket, if you do not use
the products for a long period of time.
• Store the devices in a dry place.

13.1 Battery replacement

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