Application
The FX-PCV1930 programmable digital controllers are
designed for Variable Air Volume (VAV) applications that
communicate over BACnet
controllers feature combinations of an integral digital
pressure sensor (DPT), a damper actuator, and a 32-
bit microprocessor. The controllers' small package size
facilitates quick field installation and efficient use of space
without compromising high-tech control performance.
The FX-PCV1930 controllers include an integral real-
time clock, which enables the controllers to monitor and
control schedules, calendars, and trends, and operate for
extended periods of time as stand-alone controllers when
offline from the Facility Explorer
FX-PCV controllers connect easily to the wired and wireless
network sensors for zone and discharge air temperature
sensing.
The Facility Explorer system controllers and network
sensors communicate using the BACnet protocol. The
BACnet protocol is a standard for ANSI, ASHRAE, and the
International Standards Organization (ISO) for building
controls. FX-PCV1930 Controllers are BACnet Testing
Laboratories (BTL) listed and certified BACnet Advanced
Application Controllers (B-AACs).
North American emissions compliance
United States
This equipment has been tested and found to comply with
the limits for a Class A digital device pursuant to Part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
this equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area may cause harmful
interference, in which case the users will be required to
correct the interference at their own expense.

    To daisy-chain FX-PCV1930 controllers, connect the controllers to the bus supervisor in a chain with the Ethernet cable connecting to the FX-PCV1930 at the ETH1 or ETH2 port, and connecting to the next device from the other port. Benefits of daisy-chained networks are that they require less physical wiring and new devices can be added easily to the network.
