The damp
temperature can be registered directly by a sensor if
a psychrometer is attached to your weather station. On the other hand it is
possible to calculate the damp
temperature from air temperature and relative dampness . The sensors used for this
are freely selectable. The decision criterion
for the frost warning is the damp temperature. Switching on the freeze
protection spraying is recommended, if the temperature amounts to 0°C at the
wet thermometer. The frost warning module is not strictly fixed on a warning with 0°C, but enables the input of a non-standard
value. By input of a higher temperature warning value an earlier
warning and a larger response time are possible. In order to avoid the oscillating
between frost warning and 'all-clear' signal , the
input of an all-clear threshold for the damp temperature is possible.
