Controls That Support the Mechanical System

A building automation system should do more than display temperatures. It should operate equipment according to the needs of the building, provide useful information, identify abnormal conditions, and make the system easier to manage.

We evaluate both the control system and the mechanical equipment it serves. This helps avoid situations where control changes mask mechanical problems or mechanical repairs fail to address incorrect programming and sequences.

Existing and Legacy Systems

Older control systems may continue to operate but become difficult to support because of obsolete hardware, unavailable software, limited documentation, or proprietary restrictions.

We can evaluate existing systems and develop practical options for repair, partial modernization, integration, or phased replacement.
