Variable Air Volume (VAV) control
Trox VAV controllers with Belimo components of type
NMV-D2M-TR can be connected to superordinate
DDC/BMS systems without problems with the aid of
TroxNetCom AS-interface. All users communicate over bus
cables. All data, e.g., volume flow rate values, required
value definition, operating mode, Vmin, Vmax etc.... can be
passed up to the supervision level, and changed and
displayed there.
The AS-i modules are connected to the AS-i controller
using a 2-core bus cable (e.g. yellow AS-i ribbon cable).
A maximum of 16 TNC-A2253 can be connected to an AS-i
controller, thus providing complete system of 64 flow volume
controllers. The AS-i bus cable is 100 m long as standard
and can be extended to 300 m using repeaters. The total
length of the system solution is 1580 m.
All information for the VAV controllers, e.g., actual and
required volume flow rate, damper setting, Vmin, Vmax, as
well as operating mode is available in the AS-i controller
and can be displayed and changed there.
System layout:
A maximum of 4 Trox VAV controllers with Belimo
components, e.g., NMV-D2M-TR, can be connected to an
AS-i module of type TNC-A2253 using a TNC-ZIP232 interface converter. Connection is made using a 3-core cable
(MP communication and 24 Vdc power supply). With a
cable cross-section of 1.5 mm2, the maximum permissible
cable length is 80 m including all branches.
Each interface converter of type TNC-ZIP232 has a separate
24 Vdc power supply for supplying the maximum 4 VAV
controllers and the TNC-A2253 AS-i module.
It is possible to establish an interface to a superordinate
DDC/BMS system using the fieldbus interface available in
the AS-i controller, e.g. Profibus DP, Interbus-S, or RS485.
All information for the AS-i controller can thus be processed directly in the building management system.

Advantages:
– Regulation of the fan speed not as a function of the static
pressure at a point in the system, but as a function of the
actual damper setting for the individual VAV controllers.
– Connection of VAV controller via 3-core cable
(information and power supply).
– Reduction in wiring.
– Savings during renovation projects.
– No master-slave allocation necessary.
– Change of Vmin, Vmax from the central control area or
from the AS-i controller. In this way it is not necessary to
make on-site adjustments thus saving work.
– Actual value acquisition and required value definition in a
superordinate DDC/BMS system.
– Interfacing and communication using fieldbus systems
(bus cable). The analogue boards and star-shaped wiring
used previously are thus no longer required.

Type TNC-ZIP232
25
The TNC-ZIP232 converts the Belimo MP bus protocol to
an RS232 serial interface.
Using Combicon connectors a maximum of 4 Trox VAV
controllers with Belimo components, e.g., NMV-D2M-TR
are connected via a 3-core cable (cross section 1.5 mm2).
The maximum cable length is 80 m.
The TNC-ZIP232 requires a 24 Vdc power supply that is
also used for the VAV controllers.

The TNC-A2253 SmartLogic module translates the MP bus
protocol into the AS-interface standard. It has a microprocessor and can be programmed as required in accordance with IEC61131-3.
Here project-specific data can be selected for passing to a
superordinate DDC/BMS system.
The SmartLogic module requires an external 24 Vdc power
supply. Power is provided using the power supply for the
TNC-ZIP232.
The connection to the TNC-ZIP232 unit is made via an
RS232C interface.
The TNC-A2253 SmartLogic module is connected to the
AS-interface and represents an AS-i slave that communicates
with the AS-i controller and provides all data to the controller.
