FAQ

ACS:
Parameter download
does not work, why?
Make sure that the parameter tree is expanded prior to download.
Wrong Right
Download sometimes also works with a collapsed parameter tree.
Why can I not
parameterize
the controller via HandyTool in service mode (n6)?
There are two reasons:
•
Download (HandyTool, ACS or ETS) was not exited correctly (interrupted).
•
The controller was set to "unloaded" via ETS.
Solution: Carry out a full download (via HandyTool, ACS or ETS).
Why does
a controller with thermal valves
not respond immediately when it is
enabled in the plant graphics in the ACS view and in the DESIGO graphics?
After startup, the thermal valves are preheated first.
This is not shown in the plant graphic.
Why doesn’t the
Master/Slave connection
work?
Master/slave zones must match for master and slave
Create master/slave group addresses and add communication object.
With
master/slave
configurations, why do the QAX34 room units not always show the
same
temperature values
?
The master-controller and slave-controller data is synchronized regularly. If a value
changes just after synchronization, it may be a few minutes until it is resynchronized.
