Application Controllers
HVAC Application Controller (DAC)
|
The DAC range of controllers are fully programmable, Native BACnet™ Advanced Application Controllers that communicate on an RS-485 LAN using the BACnet MS/TP protocol.
The DAC is designed for a wide-range of applications that have medium local I/O requirements. It also supports BACstats and other Delta LINKnet devices. They come in a variety of I/O configurations as set out below.
