Description
The DFC-322R3-240 is a fully programmable, Native BACnet™ Advanced Application Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol. Direct 240 VAC line voltage terminal connections are provided for 1, 2 or 3 speed fans. Room temperature can be a standard 10KΩ sensor or BACstat II, connected via a secondary LINKnet network and a 24 VAC power out connection.

DFC-322

Application

The DFC-322R3-240 is designed for fan coil control.

With 2 triac outputs and 2 analog 0-10v outputs, it

covers a wide-range of fan coil unit applications. The DFC-322R3-240 allows for sequence modifica

tions as required by the design engineer or building

owner. It provides simple, easy-to-install fan coil con

trol solutions for office buildings, hotels or residential

buildings.

Features

—Native BACnet firmware
—BACnet MS/TP communications
—Stand alone operation or on BACnet
—Fully programmable in GCL+
—Pre-loaded fan coil application database
—Direct connection to BACstat II (DNS-24 or DNS-24L) —2 tri-state and 2 analog outputs for relay actuation —3 relays rated for motor loads to control 1-, 2- or 3-

speed fans, complete with interlocks and time delays

for equipment protection
—Slim design fits into narrow fan coil units
—Power supplied by power mains (on-board 24 VAC

transformer included)
—Derived Network Addressing (DNA) for simple inte

gration into a standard network architecture —Service port
