Brief description
Application
The digital VAV-Compact has PI control characteristics and is used for pressure-independent
control of VAV units in the comfort zone.
Mode of operation
The actuator is equipped with an integrated interface for LONWORKS®. The actuator can be
directly connected and controlled with LONWORKS® via a FTT-10A transceiver.
Converter for sensors
Connection option for a sensor (active sensor or switching contact). In this way, the analog
sensor signal can be easily digitised and transferred to LONWORKS®.
Pressure measurement
Actuator
VAV – variable air volume
Test function / test display
Operating and service devices
Assembly and connection
OEM factory settings
Maintenance-free, dynamic, differential pressure sensor technology, proven in a wide range of
applications, suitable for use in offices, hospital wards, alpine hotels or cruise liners.
Three versions available, depending on the size of the VAV unit: 5 / 10 / 20 Nm.
– Rotary actuator, depending on size
– Linear actuator 150 N with 100, 200 or 300 mm linear motions
The VAV-Compact is supplied with its modulating setpoint by a room temperature controller via
LONWORKS®. This facilitates demand-related, power-saving ventilation in individual rooms or
zones of air conditioning systems. The operating range (min und max) can be set either locally
with PC-Tool or using the LNS plug-in available from Belimo.
The VAV-Compact features an LED with a ready display for commissioning and functional
checking as well as a service mode with air shortage, excess air and setpoint = actual value
display with LEDs.
Belimo PC-Tool, remote control or ZTH-VAV, plugged into the VAV-Compact.
The VAV-Compact, which is assembled on the unit by the OEM, is connected using the prefabricated connecting cable.
The VAV-Compact is mounted on the VAV unit by the unit manufacturer, who adjusts and tests it
according to the application. The VAV-Compact is sold exclusively via the OEM channel for this
reason.

Via this input variable, the set volume is specified for the VAV
controller in % Nom of the VAV unit.
This variable is normally linked to the output variable of an HVAC
controller.
nviActuateState
SNVT_switch
Via this input variable, a preset volume is specified for the VAV
controller (in % Nom of the VAV unit).
Note on priority: The last variable that was active, either
­nviActuatorState or nviRelStpt, has priority.

or the damper blade and can be used to display the position or for
service purposes.
nvoAbsAirFlow
SNVT_flow
This output variable shows the current volumetric flow through the
corresponding VAV unit and can be used for control and display
purposes.
Open loop sensor object #1
A sensor can be connected to the air volume controller. An active
