Connection plan
For configuration purposes, the specifications for the air volume box
must be loaded into the drive using SAUTER CASE VAV. The data
below are required for this purpose as a minimum.

Minimum and maximum air volume (
min
and
max
) via command signal (AI01)
The
min
and
max
values, which should be parameterised using
software, impose an upper and a lower limit on the command signal
c
qV.s
. The values to be set for
min
and
max
are entered as either
percentages or absolute values. If absolute values are entered, the
plant-specific differential pressure values in pascals are calculated
using the equation below. Without an external command signal, the
set
min
value becomes the setpoint. Minimum and maximum air
volume values are overridden using digital inputs. In addition, the
setpoint is dependent on the logical status of the command variable
and the assigned forced operation.
