Unitary & VAV Controllers
What makes Computrols Unitary controllers unlike any other on the market?
The UNI-C is the direct replacement for most of our legacy VAV products. It is available in 3 configurations depending on your need for an actuator and/or pressure pickup. It communicates using our BASnet protocol and is easily identifiable by the rotary dials used to set the address.
You have complete control over the I/O on this controller and can program it with any sequence of operation you like. You can also use any existing Unitary or VAV templates you may already have.
This product features a Belimo motor with a 5-year warranty, and the electronics, like all Computrols products, feature the industry’s only lifetime warranty.






What makes our VAV controllers unique?
Computrols Variable Air Volume (VAV) line provides both air flow control and measurement for a complete VAV solution. With an Application Specific design, setup and configuration are quickly accomplished with our free VAV Utility. Our VAV line is available in 3 configurations:
- VAV-B-AP – with actuator and pressure pickup
- VAV-B-P – without actuator but with pressure pickup
- VAV-B-X – without actuator and without pressure pickup
All models utilize the Opto communication protocol by default – BACnet and Siemens FLN versions are available as an option.
As with all Computrols products, Computrols offers a lifetime warranty on the electronics we manufacture. These controllers are designed and manufactured at our corporate headquarters in Gretna, LA, enabling our team to assure the highest level of quality control.

UNI-C-AP Overview

Add an optional damper actuator using either analog or binary outputs.
Add an optional damper actuator using either analog or binary outputs.
Small enclosure allows you to easily mount controller directly to VAV boxes.
Two decimal rotary switches (0-9) allow simple addressing – no hex, no binary.
Allows for quick replacement.
Bright on-board LEDs assist in troubleshooting.
0-5″ pressure pickup provides accurate control for sensitive low volume applications.
Unlike many VAV controllers, our controller and pressure pickup can be mounted in any orientation without loss of accuracy.
Add an optional damper actuator using either analog or binary outputs.
Supports 10K Type III thermistors or a selection of digital display wall stats.

UNI-C-X Overview

While most building automation manufacturers are known for obsoleting their solutions every 5 to 10 years, Computrols stands alone in building backward and forward compatibility into all of our products and backing them with a lifetime warranty.
While our X controllers supported up to 10Mbps communication, the LX controller supports up to 100Mbps. In other words, the LX runs 10x faster and will take only 10% of your network’s bandwidth as compared to the X-line.
