Product Description
The DNT-T103 is an intelligent room thermostat with a custom 3-
value, 96 segment LCD display. The DNT-T103 can communicate on
a BACnet MS/TP network or on Delta's proprietary LINKnet network.
The DNT-T103 can display a wide-range of digital or analog values,
including setpoints, temperature, air flow, heating and cooling status,
fan speed, valve and damper position, and more.
When connected on a BACnet MS/TP network the DNT-T103
functions as an independent BACnet thermostat. When connected to a
controller, on a LINKnet network, it provides a programmable remote
sensor and expanded I/O capabilities. This version's firmware can be
flash loaded over the network, and has a termination resistor that is
jumper selectable.
