FX-PCV1615/1626/1628/1630 Programmable
VAV Box Controllers Installation
Instructions
Applications
The FX-PCV1615/1626/1628/1630 programmable digital controllers are designed for controlling
Variable Air Volume (VAV) boxes. These FX-PCV Variable Air Volume Modular Assembly (VMA)
controllers feature combinations of an integral digital pressure sensor (DPT), a damper actuator,
and a 32-bit microprocessor. The FX-PCV1626 has an actuator but does not contain a DPT. The FX-
PCV1628 model has a DPT but does not contain an actuator. The controllers' small package size
facilitates quick field installation and efficient use of space without compromising high-tech control
performance. These FX-PCV controllers connect easily to the wired and wireless network sensors for
zone and discharge air temperature sensing.
Communications protocol
The FX-PC family controllers and network sensors communicate using the standard BACnet
®
protocol, based on the ANSI/ASHRAE 135-2008. The BACnet protocol is a standard for ANSI,
ASHRAE, and the International Standards Organization (ISO) for building controls.
FX-PCV controllers are BTL-listed as BACnet Application Specific Controllers (B-ASCs).
The Controller Configuration Tool (CCT) can be used to switch the Field Bus communications
protocol in supported FX-PC Controllers to be either the standard BACnet MS/TP or the N2 protocol.
All new controllers use either BACnet MS/TP as the default communications protocol, or BACnet/
IP. Switchable communications protocols in the MS/TP models provide a cost-effective upgrade and
modernization path for customers with existing N2 controllers.
The Modernization Guide for Legacy N2 Controllers (LIT-12012045) and the controller-specific
documentation provide installation and commissioning support and include tips for efficient
and safe replacement. Refer to the N2 Compatibility Options chapter of the Controller Tool
Help (LIT-12011147) for information about mapping N2 Objects in controllers with switchable
communications protocols.
The N2-capable FX-PC Controllers can be used as functional replacements for legacy N2 controllers.
The N2-capable FX-PC Controllers:
• have the I/O quantities and characteristics of the FX-PC family controllers
• must be programmed with CCT, which has programming capabilities that are similar (but not
identical) to HVACPro, GX9100, GPL, and other legacy tools
• support SA Bus devices
• support FX-WRZ wireless sensors from the controller using the FX-WRZ7860 receiver when
configured for BACnet MS/TP communication
The N2-capable FX-PC controllers:
• do not support Zone Bus (for example, TMZ sensors and M100 actuators)
• do not support passthrough in the commissioning mode
• do not support remote downloading or commissioning using BACnet routing
• do not support wireless connection to the N2 bus
