Features  

• Uses BACnet MS/TP network communication. 

• EIA-485 communications network. Capable of baud rates between 9.6 and 115.2 kbits/s. 

• Capable of stand-alone operation, but can also use BACnet MS/TP network communications. 

• Sylk™ bus for use with Sylk-enabled sensors. 

• Support for up to 30 controllers per BACnet MS/TP segment. 

• Field configurable and programmable for control, input, and output functions using the NIAGARA FRAMEWORK® software. 

• Function Block engine, which allows the application designer to program the controller to perform a wide variety of HVAC applications. 

• Built-in Zone Control functions include a remote wall module interface and a scheduler. 

• Pressure-independent or pressure-dependent single or dual duct Variable Air Volume (VAV) control as well as Unitary equipment control. 

• Microbridge air flow sensor with dual integral restrictor design (PVB0000AS, PVB4022AS, PVB4024NS, PVB6436AS, and PVB6438NS). 

• Easy user access to air flow sensor inputs. 

• Actuator (PVB0000AS, PVB4022AS, and PVB6436AS) mounts directly onto VAV box damper shaft and has up to 44 lb-in. (5 Nm) torque, 90-degree stroke, and 90 second timing at 60 Hz. 

• All wiring connections are made to removable terminal blocks to simplify controller installation and replacement. 

• Both controller housing and actuator are UL plenum rated.
