The DNT-T221 is an intelligent room thermostat with a custom 3-value, 96 segment, LCD display. The DNT-T221 can communicate on Delta’s LINKnet network or directly on a BACnet MS/TP network.

The DNT-T221 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-T221 functions as an independent BACnet thermostat. When connected to a Controller, on a LINKnet network, the DNT-T221 provides a programmable remote sensor and expanded I/O capabilities.



The DNT-T22 is designed to be a low cost solution for

control of unitary equipment. The DNT-T221 has

built-in algorithms for configuring VAV, VVT, fan

coil/unit ventilator, heat pump, radiation and humidifi

cation applications.

The DNT-T221 may also be connected to a LINKnet

network to provide remote sensor and expanded I/O

Thermistor Input - 10kΩ at 77°F (25°C) Accuracy +/-0.36°F from 32-158°F (+/-

0.2°C from 0-70°C)

Display resolution of 0.1°

Stability 0.24°F over 5 years (0.13°C) Humidity Sensor

Accuracy of +/-2% RH from 0-100% RH

(25°C, Vsupply = 2.6Vdc)

Display resolution of 0.1%

Stability of +/- 1% RH (typical at 50% RH over

5 years)

Note: Extended exposure to >90% RH causes

a reversible shift of 3% RH Inputs

2 Universal inputs - 10 bit (supporting 0-5v,

0-10v, 10kΩ)*

*Note: the humidity option uses one of the

available universal inputs Outputs

2 Analog outputs, 0-10VDC @ 20mA

1 Binary triac output (supporting binary, PWM,

or tri-state)
