HVAC Controls Built in America and Backed for Life
We design and manufacture HVAC controllers at our Louisiana headquarters and back every one with a lifetime warranty.
40+ years in building automation

designed and manufactured in Louisiana
Controls That Work for the Building Owner, Not Against Them
Lifetime Warranty
Every controller we manufacture is covered for life. We build them right, then stand behind them.
Your Investment, Protected
A controller built today works on a system installed decades ago, and the reverse. When you’re ready to upgrade, our buyback program credits the Computrols controller you already own toward its replacement.
Built for Your Engineers
Plain-English If/Then programming your team can run themselves, with full access to their own system.
Integrate First. Replace When You're Ready.
Our controllers speak over 25 protocols natively, including BACnet, Modbus, Johnson Controls N2, Siemens FLN and CSI I/NET, along with other proprietary ones. Bring the system you have onto one simple front end today, then replace failed controllers one at a time with Computrols hardware on the same network.
It’s a path away from proprietary systems that’s less intrusive, and more within reach, than most owners expect.

Our HVAC Controllers
LX Controllers
Our core controller family. Flexible and powerful, in sizes from 8 to 64 points to fit the equipment you’re controlling.
Serial Connector
Our most robust integration product. Connects up to three existing networks, each in its own protocol, and mounts almost anywhere.
Unitary and VAV Controllers
VAV-B and UNI-C controllers for terminal units and unitary equipment.
Designed From 40 Years in the Field
Innovations like these come straight from the field experience of Computrols founders Roy and Kevin Lynch.
Two-Piece Board Design
Replacing and rewiring a controller shouldn’t be a project. Our two-piece board design lets even a novice change out a board in under 2 minutes:
- Power off the controller
- Remove the Ethernet cable
- Remove the existing controller
- Replace with the new controller
- Set the IP address
- Reconnect the Ethernet cable
- Power on the controller
4-in-1 Points
On our LX controllers, any point can be set in software as an Analog Input, Analog Output, Binary Input or Binary Output. No jumpers required.
No Product Churning
In 40+ years we have yet to obsolete a product. No planned obsolescence, and our integration solutions even support many competitors’ “obsolete” products.
Most Economical to Own
Count every lifecycle cost and it adds up: simple hardware and software, 24/7 technical support and a lifetime warranty.
You Own It
Your controllers and CBAS belong to your building, with no required recurring licenses. Support comes from us or an authorized Computrols distribution partner, backed by our 24/7 technical support line.
