Product Description
The BACstat II is an intelligent 4-button room sensor/thermostat with a
custom 3-value, 96 segment LCD display that is used with Delta's product
line of BACnet Application Controllers. It is capable of displaying a wide
range of digital or analog values, and is capable of communicating on Delta's
proprietary LINKnet network or directly on a BACnet MS/TP network.
When connected to an Application Controller on a LINKnet network it
provides programmable remote sensor and expanded I/O capabilities to the
controller. When connected on an MS/TP network it functions as an
independent BACnet sensor device or a small local controller.
The DNS-24 model does not have additional I/O and built-in control strategies, while the DNT-T103 has 1
extra input, 3 binary outputs and a number of built-in application control strategies. The DNT-T221 has 2
extra inputs, 2 analog and 1 binary outputs and built-in application control strategies. As a result, the DNT-
T103 and DNT-T221 BACstats are capable of simple stand-alone control when directly connected on an
MS/TP network. When connected to a LINKnet network, the additional I/O may be MUXed or otherwise
controlled from the Application Controller it is connected to.
