ASI Controls is a California-based building automation, HVAC controls, direct digital control (DDC), and energy management technology company headquartered in Pleasanton. Founded in 1986, the company was established to apply networked microprocessor technology to energy management and building control systems. Today, ASI Controls manufactures digital control hardware and software designed for HVAC, building automation, energy management, lighting control, and light-industrial applications. The company works with building owners, system integrators, resellers, and OEM partners to deliver configurable control solutions.

ASI Controls specializes in BACnet-based direct digital controls (DDC) for heating, ventilation, air conditioning, and building environmental management. Its systems allow users to monitor building conditions, receive alarms and notifications, adjust temperature setpoints, manage schedules, and access control information remotely through web-enabled interfaces. The company’s products are designed to support interoperability with technologies and protocols including BACnet, LON, Modbus, OPC, and Niagara-based JACE systems.

A key aspect of the ASI Controls product strategy is backward compatibility. The company states that current products remain compatible with ASI products introduced since 1992, allowing customers to upgrade functionality without necessarily replacing an entire legacy control infrastructure. ASI also provides a five-year limited warranty on its ASIC controllers and core accessories.

The company’s product and solution portfolio supports building automation systems, HVAC controls, energy management, lighting controls, web-based monitoring, alarm management, and OEM equipment controls. ASI products can be applied to individual mechanical systems such as chillers and air-handling units, as well as larger building automation networks containing thousands of controllers and devices.

ASI Controls also provides technical support, training, reseller resources, and system-integrator support. Its headquarters is located at 5111 Johnson Drive, Pleasanton, California, with the company continuing to operate as a privately held controls manufacturer.
