Information on air pressure
The unit for air pressure is Pascal (Pa).
1 Pa = 0.01 hPa = 0.01 mbar
The air pressure is specified as "normal air pressure" or as "barometric pressure".
The normal air pressure is the pressure compensated for height and temperature. The
barometric air pressure is the pressure measured directly by the sensor (without com-
pensation).
6.14. Air pressure threshold values
Activate the required air pressure threshold value. The menus for setting the threshold
values are displayed.

Threshold value
Set, in which cases threshold values and delay times received are to be kept per object.
The parameter is only taken into consideration if the specification/ setting by object is
activated further down. Please note that the setting "After power restoration and pro-
