Description
The DNT-T103 is an intelligent room thermostat with a custom 3-value, 96 segment, LCD display. The DNT-T103 can communicate on Delta’s LINKnet network or directly on a BACnet MS/TP network.

The DNT-T103 can display a wide-range of digital or analog values including setpoints, temperature, airflow, 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, the DNT-T103 provides a programmable remote sensor and expanded I/O capabilities.

Application

The DNT-T103 is designed to be a low-cost solution

for control of unitary equipment. It has built-in,

configurable algorithms for VAV, VVT, fan coil/unit

ventilator, heat pump, radiation and humidification

applications.

The DNT-T103 may also be connected to a LINKnet

network to provide programmable remote sensor and

expanded I/O capabilities.
