Assortment / System Description

VAV compact controllers

The VAV* compact controllers are used to control variable or constant volumetric

air flow. They are certified by KNX and can be used in connection with all KNX

devices which, in terms of application, are compatible.

* VAV = Variable Air Volume

Features of VAV compact controllers:

• Actuator with built-in high-precision differential pressure sensor

• Rated torque 5 or 10 Nm (see product nos.)

• Angular rotation of air damper mechanically adjustable between 0° and 90°

• Control unit configurable for VAV or CAV

• Configurable as an individual controller (for one room) or for cascade control

• With connecting cable for operating voltage AC 24 V or KNX bus

• Communication via KNX in LTE mode, e.g. for VAV system solutions between

primary air handling (RMU7x0B) and room thermostats (RDG400KN)

• Communication via KNX in S-mode (integration of third-party devices)

Use:

• Supply air temperature control

• Extract air temperature control

• Supply-extract air cascade control with …

– 1-to-1 ratio control,

– over-/underpressure ratio control,

– over-/underpressure differential control.

Usually, the OEM fits the entirely factory-configured VAV compact controllers in the

box. This simplifies commissioning on site.

However, if changes to the configuration or settings become necessary, the VAV

compact controllers can be commissioned in KNX networks via the following tools:

Communication Planning and commissioning tool

KNX LTE mode Service tool OCI700.1 with service and operating software ACS790

KNX S-mode ETS3 or ETS4, see KNX Association http://www.knx.org/

PC via AST11 PC software ACS941 (service and maintenance) via interface converter AST11
