HVAC Control




The Field Commander Building Automation System provides a range of controllers for any type of general HVAC equipment.  Universal Unitary Controllers are available in a variety of input/output configurations and are software programmable so that custom control programs can be loaded for specific types of equipment.  A complete suite of Enterprise Software provides operator access to the system as well as extensive reporting capability.  Specialized controllers augment the general controllers, providing hardware and software capabilities designed for specific equipment needs.


Control Features


Distributed Intelligence

No centralized point of failure.  Our controllers can operate independently or as part of a complete system.  Each controller has it's own battery-backed clock and scheduling capability.

Reliable Operation

Our controllers are designed with components selected for their reliability and forgiving tolerances. 

Industry Standard Integration

The Field Commander Building Automation System integrates with other systems using industry-standard network methods and protocols such as BACnet and XML Web Services

Modular, Scalable, and Flexible Control Network

The Field Commander Building Automation System can scale from the smallest to the largest facilities simply by adding controllers to the network.
