The change to the value "UP", with priority 
"1", has precedence and is registered as the 
Present_Value in the object. 
The value "UP" is assigned priority level 
"6", which is intended for time-limited off 
and on switching. The blinds are pulled up. 
The time of the change in status is recorded 
and the 5 minutes of the minimum switch-
ing time begin.

If, after some time, the priority level "1" is 
overwritten with "ZERO", the status of the 
minimum on/off switching time is also 
overwritten with ZERO and reset. 
The value in the next higher priority level 
"7" is taken over as the "Present_Value" 
with "DOWN".

600 sec.
While the Minimum_Off_Time is running, 
no switching can take place. Not even a 
switching process with a higher priority of 
"2" can cause a change in status. 
Not until the Minimum_Off_Time of 10 
minutes has passed will the value pick up 
the higher priority. In this case, the blinds 
go up ("UP"). 
To reset a task, a WriteProperty containing the value ZERO must be resent. If 
all priority levels are assigned the value ZERO, the standard value will be as-
sumed.
