RTU38 Advanced Rooftop Controller

Product Overview

The RTU38 Advanced Rooftop Controller is intended for mechanical equipment OEMs who want to enhance the operation of packaged rooftop units (RTUs) through advanced sequences that reduce energy, or continually check for faulty operation and report accordingly. The RTU38 is capable of monitoring, controlling, analyzing, or energy optimizing the operation of constant volume or variable volume multistage heating/cooling rooftop units or air handlers.

The RTU38 is a 38-point rooftop controller with dual Ethernet ports and an isolated MS/TP port that provides BACnet/IP and BACnet MS/TP client/server capability. A powerful CPU with a Linux OS makes this an ideal controller for OEMs who want to develop custom equipment for applications, such as economizers, demand control ventilation, variable air volume control, and multi-stage heating and cooling.

Product Details

The controller complies with the B-ASC device profile, having a mix of sixteen universal inputs, ten binary inputs, four analog outputs and eight relay outputs. Pin and socket connectors speed controller installation in the RTU.

The device is fully web page-configurable, and freely programmable using Sedona's drag-and-drop programming methodology of assembling components onto a wiresheet to create applications. A library of sequences exists for economizing, demand control ventilation, optimal start, supply air pressure reset, and exception reporting to the cloud. The unit can be programmed using the Sedona Application Editor (SAE) in Contemporary Controls' free BAScontrol Toolset. Rugged design, low profile, and wide temperature operation make it suitable for indoor or outdoor use.
