Frost warning - When the radio sensor measures a temperature of
between + 1 °C and -1 °C, a risk of frost exists and a snowflake symbol
flashes. If the temperature falls below -1 °C for a constant period of
time, the snowflake symbol is displayed steadily.
Please note: Even if the temperature alarm is not displayed,
there is always a risk of frost/black ice with temperatures
around freezing point. The outside sensor can only measure the
local temperature at the installation site.
Only if a radio sensor is in use. With a frost alarm, the radio
sensor with the lowest sensor number is always evaluated.
If the symbols for the weather forecast start to flash and the air pres-
sure falls, this is an indication of weather deterioration, e.g. because
of a storm front closing in.
However, the requirement for a correct display is that you have set
the air pressure at your location, see page 12.
