Sensor
The pressure sensor type is specified to enable the pressure range to be adapted.
Actuator
The actuator type is specified to enable the running time characteristics to be adapted.
Control – reference signal w,
volumetric flow actual value signal U5
The reference signal w and the volumetric flow actual value signal U5 are adapted to the MCR
system.
Selection: DC 0...10 V / DC 2...10 V / adjustable (sequence matching in the 0...10 V range)
Calibration –
nom
The
nom
values are specified and fixed-programmed by the unit manufacturer.
Each VRP-M system solution is optimally adapted to the VAV unit by means of the
nom
setting.
nom
corresponds to the maximum volumetric flow of the VAV unit at which the pressure drop
and noise are still within the permissible operating conditions. The
nom
setting is specified by
the unit manufacturer.
Replacement orders
If replacement devices are ordered, they must be parameterised beforehand by the OEM at the
factory according to the installed system. The VRP-M is sold exclusively via the OEM channel for
this reason.
