Computrols Building Automation Software (CBAS) is the simplest building automation system software to install, program, maintain, and operate. From its inception, CBAS was built with the end user in mind, enabling facility managers to make changes to their systems without the guidance of a trained technician. This approach has all but eliminated the need for our customers to carry hefty maintenance contracts like those required by many of Computrols’ competitors.

CBAS is designed to control and monitor HVAC, lighting, access, and fire alarm systems. As with all of our products, Computrols’ research and development team is continually bringing new advancements to CBAS with the goal of making the job of the facility manager as easy as possible. Many of the features in the software today have come from minds of our most innovative customers.

Auto-tuning PID

Control Loops No need to grind over calculations to make sure you don’t overshoot setpoints. The decisions are made for you.

English Language If/Then Logic

No codes to memorize. As the needs of your facility change, it’s simple to program CBAS. An example of this logic might be “if outside air temperature is greater than 85 degrees, then start chiller.”

Multiple Views

CBAS offers three viewing options: hardware view, text view, and graphics view. Each offers a unique and thorough view of your system as a whole.

Internet Capability

CBAS comes equipped with an Internet protocol (TCP/IP) that can be used for controlling your system from anywhere in the world. TCP/IP also allows for networking multiple workstations.

Password Customization

Use custom passwords to ensure the integrity of vital data. This also provides the system administrator with a complete list of lockouts to choose from.

Controller Downloading

Allows the head end to upload all information to the controllers. This enables the controller to be truly stand-alone.

Remote Access

Having the ability to access your BAS via your mobile devices and desktop computers can be invaluable for engineers and facility managers on the move. CBAS Web gives you access anywhere, anytime.

Overtime Air and Tenant Billing

Your tenants can utilize CBAS Web’s user-friendly interface for overtime air and tenant billing. This feature automates the entire process, automatically sending invoices to property managers at the end of the month to be distributed to their tenants.

Unlimited History for All Points

Rather than having to set up trends, CBAS allows you to record histories on all of your points, all of the time, from the inception of the Computrols system. Your only limitation is hard drive space.

Real-time Energy Dashboards

We know you don’t have time to dig into your energy usage on a daily basis, so CBAS Web gives you a quick, visually appealing view at the points that matter most to you. CBAS Screenshot
