Alarm
There are two parameterizeable alarms, when the alarm function was activated. The
frostalarm is for the notification of the lower temperatures and the heatalarm for the
notification of the upper temperatures. Both alarms have a separate communication object
with the size of 1 Bit.
The chart shows the relevant communication objects for the alarms:
Number Name
3 Frostalarm
4 Heatalarm

Messages
The message function is almost identical to the alarm function, but less in its priority. There
are two messages available, when the message function was activated. These two messages
can be parameterized separately. The dynamic range of the message function is much bigger
than the one of the alarm function. So it is also possible, to realize running turn over. Both
messages have an own communication object of the size 1 bit. These communication objects
are shown in the chart below:
Number Name
1 Higher message value
2 Below message value
