Description

The DNS-24 is a smart room sensor that can optimize user comfort while reducing energy consumption. It is a simple to install, and cost effective package for advanced, automated, control. With an LCD display and intuitive pushbutton interface, the DNS-24 communicates over an RS-485 LAN using BACnet® MS/TP or Delta’s LINKnet protocol.

The DNS-24 has multiple sensor options including temperature, humidity, motion, and a self-calibrating CO2 sensor.

DNS-24/C24/M24

Application

The DNS-24 is suitable for a wide range of space sensing applications, from basic temperature sensing to indoor air quality and occupancy sensing.

The DNS-24 provides mechanical equipment controllers the information needed to drive advanced control algorithms, such as demand control ventilation, for optimum user comfort with minimum energy consumption.
