WHAT IS THE NB-VAV?
-
The NB-VAV model controllers are variable air volume (VAV) and constant air volume (CAV) terminal box digital controllers that comply with ANSI/ASHRAE Standard 135-2001, BACnet.
-
There are five (5) NB-VAV controller types (refer to Table below) that can be employed in different applications.
-
FEATURES OF THE NB-VAV:
-
Can communicate with third party BACnet-MS/TP devices such as Unitary Controllers or Area Controllers over EIA-485 (RS-485)
-
Optically isolated triac solid-state relay outputs with metal oxide varistors (MOV) (NB-VAVta and -VAVtf)
-
Mechanical relays equipped with a tranzorb protection device to suppress transients and contact arcing (NB-VAVr, -VAVra, and -VAVrf)
-
Analog outputs with 0-10VDC range, 8-bit resolution
-
15-bit resolution universal inputs (UI)
-
Automatic settings for VAV or CAV control mode
-
Separate heating and cooling options for supply mode
-
Motor Management TechnologyTM (MMTTM) for monitoring, identifying, and correcting motor shorts
-
An integrated Belimo® LM24-10P-M feedback actuator that allows you to monitor the position of the damper at all times or an integrated Belimo LM24-M actuator (the NB-VAVr does not have an actuator)
-
An on-board, solid-state airflow sensor that measures the airflow and enables the calibration of airflow measurement for a wide range of VAV and CAV terminal box sizes and types
-
Flash updates through NB-ProTM for easy incorporation of the latest firmware and application templates.
