DNT-T103/H103B
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.
Features:
- Native BACnet™ firmware
- BACnet MS/TP or LINKnet communications
- Configurable 3-value, 96 segment, LCD display (with optional backlighting)
- 4 Configurable push buttons
- Controller firmware can be flash loaded over the network
- Network termination is jumper selectable on each device
- Derived Network Addressing (DNA) for simple integration into a standard network architecture
- Field selectable applications
- Service port
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.
Accessories:
- RPT-768—Delta Network Repeater for BACnet MS/TP
- CON-768—Delta Network Converter
