Heating, Ventilation & Air Conditioning SystemsOn average, HVAC operation accounts for nearly half of a commercial facility’s energy consumption. Having the proper HVAC controls system in place can generate significant energy and cost savings for building owners. More importantly, HVAC control is responsible for the comfort and health of a building’s occupants as it provides temperature control, fresh air circulation, and filtration.

Computrols HVAC controls are the backbone of large building automation systems, specifically made to meet the challenges of today’s largest and most demanding facilities. Some of the unique features of our DDC controls include:

» Lifetime warranty
» Integration to open and proprietary systems
» Two-piece board design
» No product churning
» 4-in-1 points

Lifetime Warranty

You read that right. All of our HVAC controllers come with the industry’s only lifetime warranty. If one of our controllers fail under normal working conditions, our customers send it back to be repaired or replaced. Since Computrols started manufacturing its own line of hardware in the early 90s, quality and simplicity have always been at the core of everything we create. We ensure this high-level of quality assurance by manufacturing all of our products at our corporate headquarters, in the USA.


Computrols has been integrating to third-party HVAC control systems for nearly three decades, and our DDC controllers have continued to open up new gateways to integration. Computrols’ DDC controllers give our customers the ability interface with both open and proprietary systems. Not only that, but often times, as the existing sub-controllers fail, they can be replaced by Computrols’ lifetime-warranty controllers on the same communication trunk. Our controllers are capable of integrating with devices that communicate via BACnet, Modbus, Johnson Controls’ N2, Siemens’ Floor Level Network, CSI I/NET, and more.

Two-Piece Board Design

When HVAC controllers are being replaced, removing each controller and rewiring a new one can be cumbersome to say the least. Given the field experience of Computrols’ founders, we decided to make this easier…much easier.

Computrols’ unique, two-piece board design allows even a novice to change out a board in less than 10 minutes.

  1. Power off the controller
  2. Remove the ethernet cable
  3. Remove the existing controller
  4. Replace with new controller
  5. Set the IP address
  6. Input ethernet cable
  7. Power on the controller

4-in-1 Points

On Computrols’ X-Line and LX HVAC Controllers, any point can be configured through software to be Analog In, Analog Out, Binary In, or Binary Out – no jumpers required. Innovations like this are a direct result of the field experience of Computrols’ founders, Roy and Kevin Lynch.

No Product Churning

In our 30+ years of doing business, Computrols has yet to obsolete one of its products. While other BAS manufacturers are building planned obsolescence into their products, Computrols is providing you with an infrastructure that will last a lifetime. Computrols even supports many of our competitors “obsolete” products through our integration solutions.

The Most Economical HVAC Controls Solution

When all lifecycle costs are considered, Computrols HVAC controls solution is, without a doubt, the most economical to own system on the market today. Our simple-to-use software and hardware combined with our free 24/7 technical support line give our customers the tools they need to operate their own building automation system.
