Hysteresis between
threshold values,
*1%
If the command value of the room
temperature control has undershot the
threshold value minus the hysteresis,
the fan controller switches back to the
previous level.

Due to fan motors' inertia, as a rule
there is a limit to how short the time
intervals for switching the fan levels can
be, i.e. there is a limit to how quickly the
fan speed can be varied. If the fan
controller is working in automatic mode,
the settable "Waiting time on level
change-over" is maintained on change-
over of the levels.

To reduce the fan noise of a fan coil, the
fan level limit can be activated. The level
limit reduces the sound emissions by
limiting the maximum fan level to a fan
level value configured here (limitation
level). The limit can be switched on and
off using the "Fan, level limit" 1-bit object
and thus activated as necessary.
The parameter "Level limit" is not
checked for plausibility in the ETS,
meaning that an implausible
parameterisation is possible. For this
reason, care should be taken to ensure
that there is no limit level in the
configuration which is higher than the
actual fan levels. If a higher limit level is
configured, then the limit has no effect.

The controller provides the option of
activating a forced fan position via the
bus. With an active forced position, the
fan levels can neither be controlled nor
switched over in either automatic or
manual mode. The fan remains in the
forced state until the forced position is
removed using the bus. In this manner,
it is possible to switch the fan to a
locked and controlled state, for example
for servicing purposes.
As soon as the forced position is
activated, the controller jumps to the fan
level configured in this parameter
without any waiting time. The fan can
also be completely switched off.
Object interpretation,
automatic/manual fan
control
0=Automatic,1=Manual
1=Automatic,0=Manual
The parameter specifies the polarity of
the object for the change-over between
automatic and manual fan control.
Automatic mode is always active after a
device reset.
