Integrating Legacy Control Systems

If your facility currently has a legacy control system that needs upgrading but you don’t have the capital budget for a full retrofit, you are likely considering some form of building automation system integration. By integration, we are referring to an approach that would leverage some portion of your existing system while likely changing out some of the higher-level components such as the front-end software and/or parent-level controllers. Integration is a logical choice in this situation but before moving forward with this approach, there are some important elements that you should fully understand.

Computrols Webinar: CSI – I/NET Integration

Webinar transcript

[00:00:15.270] – Scott Holstein

Hi everybody Scott Holstein here with Computrols, welcome to our I/NET integration webinar.


For those of you who are familiar with I/NET, you know that I/NET has been around a very long time and most people have a very high opinion of their hardware and how their system works. There’s a reason why these obsolete systems essentially are still around today and people are still trying to maintain them. But today we’re going to talk about the I/NET infrastructure and some of the challenges of maintaining these systems now and then go into what Computrols does in terms of integration.

HVAC Controls Integration: One Post Office Square – Boston, MA

One Post Office Square

Computrols Distribution Partner, Dynamic Energy Controls, recently completed another large take over in an integration project at One Post Office Square in Boston, MA. This building is managed by JLL. At 525 feet, 41 stories tall and 832,000 square feet, this skyscraper is one of the tallest in the Boston skyline. With the help of their new Computrols Building Automation System, it may also become one of the most energy efficient. The building is currently Energy Star Certified and LEED Gold.

When Dynamic Energy Controls’ Chris Kelliher was brought into the picture, One Post Office Square was outfitted with an aging Johnson Controls system including DX9100s, UNTs, AHUs, XTs, NAEs, NCEs, and NCM350s. The facility’s staff found the JCI user interface Continue reading HVAC Controls Integration: One Post Office Square – Boston, MA


HVAC Controls Project: Lyric Centre – Houston, TX

The Lyric Centre, located at 440 Louisiana Street in downtown Houston, recently became one of Computrols newest customers. The building is 26 stories tall and provides approximately 385,000 square feet of commercial office space.

The Computrols Houston branch kicked off the project in October of 2017, integrating to the existing Johnson Controls system. In addition to interfacing with the existing JCI, DDC equipment, a core Computrols infrastructure is being installed. This infrastructure consists of a new headend computer, software, and lifetime-warranty controllers to replace the existing NAEs. These new DDC controllers communicate to the existing JCI equipment via N2 and BACnet protocols, enabling the building staff to monitor and control the existing JCI equipment. Computrols will also be providing additional lifetime-warranty controllers for future pneumatic to DDC floor conversions. Continue reading HVAC Controls Project: Lyric Centre – Houston, TX


What to Do When Your Building Automation System Becomes “Obsolete”

Many building automation manufacturers utilize the approach of product churning and planned obsolescence to force their customer to “upgrade” to their next generation of products every 10 years or so. They go as far as to stop manufacturing and supporting any of their older products. On top of that, their new products are not compatible with legacy products. This is a concept we see in our daily lives in cell phones, Windows operating systems, and even home appliances.

In this case, building managers are forced to do one of two things: 1. Upgrade their entire system, spending tens, if not hundreds of thousands of dollars or 2. Try to buy the manufacturers legacy controllers on third-party sites such as eBay.

What these building managers do not realize is there is a third option: CALL COMPUTROLS. Computrols has been interfacing to competitors’ systems for over 30 years.

Do you have a legacy building automation system that the manufacturer no longer supports? Computrols’ integration solutions leverage the existing infrastructure while providing a simple-to-operate user interface. More times than not, this enables the operating staff to eliminate large maintenance contracts.

Is your controls manufacturer telling you that you need to upgrade your system? Don’t do it without calling Computrols first. We have countless examples of building managers that were in the same situation who saved hundreds of thousands of dollars through Computrols’ integration solutions.

Once your Computrols integration is in place, your third-party field controllers are bound to fail at some point. Rather than searching for replacements, we’ll replace them with Computrols’ lifetime warranty controllers.

Stop letting the big name building automation providers push you around. Computrols will work with you as a partner, not just a customer. Call 504-529-1413.
