Description
The DNT-VAV-DG1 package is a Native BACnet™ Advanced Application Specific Controller designed for single duct VAV applications. It consists of an intelligent LCD thermostat (DNT-T103) for control and BACnet MS/TP communication, and a remote termination module (DTM-VAV-DG1) for sensing and actuation.

The thermostat has an LCD display, four push buttons for setpoint and occupancy override, and contains a configurable VAV algorithm suitable for controlling the remote termination module. This module, which is designed to mount on the side of the VAV box, comes complete with a damper actuator, flow sensor, and housing. It also has termination points for optional control of a fan or a single stage of auxiliary reheat.

DNT-VAV-DG1

Application

The DNT-VAV-DG1 is suitable for networked or

stand-alone VAV boxes of the following types: —Single duct, cooling only
—Single duct, cooling, one-stage digital reheat —Single duct, cooling, one-stage time proportioned

—Single duct, cooling, one-stage PWM reheat —Single duct, cooling only, intermittent parallel fan

Features

—Native BACnet firmware
—BACnet MS/TP communications (DNT-T103) —Micro-processor based LCD thermostat —Integrated housing with damper assembly —Field configured VAV algorithms
—Simple air balancing and commissioning with the

thermostat keypad
—True differential pressure sensor
—Reliable, industry standard actuator —Terminal strip for connecting to the DNT-T103 —Service port
