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 40 controllers per BACnet MS/TP
segment (under 30 is recommended).
• 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.
