Honeywell PROGRAMMABLE BACNET CONTROLLER (PBC)

Programmable BACnet® Controllers (PBCs) provide

flexible, freely programmable, demand-led control

delivering tangible benefits that improve safety, reduce

energy spending, and add new levels of functionality to

today’s building management systems.

The PBC can be mounted on a Phoenix Controls Venturi

valve or in a control panel and serves as the zone controller

for offset control, comfort control, emergency control,

dynamic pressurization control, and additional

programmability that might be needed in a zone.

The PBC can also be used as a standalone control device

where additional IO and control functions are needed.

FEATURES

• BACnet® MS/TP support.

• Color-coded, removable terminal blocks to simplify wiring and replacement.

• Easy to install into cabinet, on DIN rail, or surface mount.

• Support of standard BMS protocols offering an open system for interconnectivity.

• LED status indicators:

• Small LEDs - green for communication signal transmission or reception.

• Large LEDs - Device status (Green, Yellow, Red).

• Niagara-based Function Block library and sample applications.

• Power failure detection and data recovery.

APPLICATIONS

Research Environments with High Speed VAV Fume Hoods

As part of the Critical Spaces Control Platform (CSCP), the PBC functions as the zone controller managing offset

control, temperature and humidity control, occupancy control, emergency control, and has additional programmable

logic control. Where fume hood containment and rapid airflow control really count, the PBC can manage the demands

of laboratory spaces with up to 20 high-speed valves, and 10 fume hoods monitors in one zone. Multiple temperature

zones, built-in diversity, and usage based controls can all assist in saving energy. Zone balance and offset control

managed with a one-second response speed of response, and several emergency control modes can be programmed for

flexible room sequencing. Bluetooth connection to the Phoenix Controls Flow Manager app allows support for viewing

alarms, monitoring space conditions, and making setpoint changes. The Flow Manager app is available for Android and

iOS. For more information on the Flow Manager App, see the Flow Manager App Datasheet (MKT-0518).

Life Sciences / Vivariums

Zone balance, comfort control and air change rate diversity for general research spaces are key, as well as maintaining

more natural, lower stress environments for research animals. The Critical Spaces Control Platform can manage a

uniquely broad diversity of demands within a single facility. Each PBC manages up to four standard speed venturi valves

which will support low up-front install cost without compromising controllability. Zone balance, offset control,

switching polarity of spaces (Positive to Negative or vice versa), Temperature control, Humidity control, and other

sequencing can all be accomplished with one PBC.

High-Purity Manufacturing Environments

Precision pressure control coupled with high air change rates are critical for high-purity manufacturing, but cost of

operations can impact the bottom line. The Critical Spaces Control Platform helps maintain the desired environment

while offering the flexibility to re-purpose spaces quickly, manage air exchange based on monitoring ISO-class and

environmental quality parameters, reliably and repeatably cascade pressures from space to space without having to

rebalance or create deviations. The PBC’s flexibility in supporting multiple valves, whether high speed or standard

speed, ensures a solution with a wide array of options for demanding spaces.

Healthcare (including operating theaters and isolation spaces)

From Surgical suites, patient rooms, to Intensive Care Units (ICU’s) and Compounding Pharmacy, nowhere is a

comprehensive environment control platform more necessary. The PBC maintains the proper flow control relationship

between all valves, ensuring proper offset control for all spaces while allowing variation in flow for more room state

flexibility. Ventilation flexibility with CSCP easily allows the Hospital facilities to manage ventilation requirements due

to more efficiently to address occupancy, environmental quality, pandemic modes, changing temperature demands, to

even customized control for surgeons and or surgical procedures in the Operating room theaters.
