Planning and application
General
After a change of the fan control (speed control or changeover control) of the
fan type, a full reset of the Room Master is required in order to avoid
incorrect function. This full reset has the same effect as reset of the device in
the ETS.
In this case the objects are normally written with the value 0. The timers stop
and are set to 0.
Status objects are set to 0 (with the exception of automatic, if it is active) and
contacts are opened.
With the normal download, where no re-parameterisation of the fan type and
fan control has occurred, an action has the effect that in the ideal case no
unwanted reactions are initiated and thus normal operation is not influenced.
Object values remain unchanged. Timer will not operate and must only be
restarted. Status values are updated and sent. The contact position remains
unchanged and only changes with the next switch command.
Note
After a download with a change, the application complies in behaviour to
a reset of the device in the ETS.
Switch contact output
The object value Staircase lighting time remains unchanged.
The object value Disable function time remains unchanged.
Exception: The object value is set to 0 if there is no assignment to
the communication object.
Note
Otherwise the block for the function Time is removed, if the
communication object Disable function time is not available.
The switch contact output will otherwise use the new parameters.
The object value Permanent ON remains unchanged.
The switch contact output remains unchanged.
