The function is used to protect blinds or other facade products from mechanical
damage caused by icing. The application function reads the values of the
outside temperature sensor and precipitation detector. Frost protection is
activated if the outside temperature drops below a set limit and precipitation is
reported.
In the event of a frost warning, the blinds products are deployed to a configured
position. A position can also be configured for a sensor fault as well.
Frost protection is automatically reset if no precipitation is reported during a
configured period or the outside air temperature is above the limit value during
a configurable period.
