How Danfoss’s New Programmable Controller Platform Can Revolutionize the HVAC Industry

The HVAC industry is facing unprecedented challenges and opportunities in the wake of the global climate crisis, the rising demand for energy efficiency, and the increasing digitalization of buildings and systems. To meet these challenges and seize these opportunities, HVAC manufacturers and end users need smarter, more flexible, and more secure solutions that can adapt to changing needs and regulations.

That is why Danfoss, a global leader in engineering solutions, has introduced the Alsmart™ Universal Controller platform, a new generation programmable controller portfolio for the HVAC market. The Alsmart platform is designed to meet today’s advanced needs as well as tomorrow’s, combining flexible and advanced control features, multiple communication options, the highest levels of cybersecurity protection, and powerful and easy to use programming tools.

What is Alsmart and what can it do?

Alsmart is a modular and scalable platform that consists of a base controller unit and optional input and output modules that can be easily added or removed using a patented side-by-side connector method. This provides the ultimate in flexibility when controlling HVAC components like valves, sensors, compressors, energy meters, switches, and other devices.

The base controller unit has a powerful processor and memory that can handle the most demanding applications and algorithms. It also has a built-in display that can be snapped on or off using a magnet, and can be used to download firmware updates, commission, and debug the controller.

The Alsmart platform supports multiple standard programming languages (IEC 61131-3) in a familiar though innovative environment. Users can program applications and algorithms using graphical, textual, or hybrid methods, and can easily reuse and share code across different projects and devices.

The Alsmart platform also offers multiple communication options that allow rich data sharing and remote access. Users can choose from a wide variety of standard protocols including BacNet, CanBus, Modbus, SNMP, HTTPS, and MQTT/S. These protocols not only enable connections to other devices, systems, and cloud platforms, but also allow remote commissioning, live debugging, and fleet software management.

Moreover, the Alsmart platform ensures the highest cybersecurity protection by adhering to stringent IEC 62443-4-2 cybersecurity standards. The platform uses encryption, authentication, and authorization mechanisms to prevent unauthorized access and data breaches.

What are the benefits of Alsmart for the HVAC industry?

The Alsmart platform is an enabler that allows HVAC manufacturers and end users to deliver sustainable solutions with the highest efficiency while driving to reduce energy consumption and CO2 emissions in green buildings. The platform can be used for a variety of HVAC applications, such as data center chillers, rooftop HVAC units, heat pumps, or DOAS systems.

Some of the key benefits of the Alsmart platform are:

  • Flexibility: The Alsmart platform can be customized and configured to meet the specific needs and requirements of different applications and customers. Users can easily add or remove input and output modules, program applications and algorithms, and choose communication protocols.
  • Performance: The Alsmart platform can handle complex and demanding control tasks with high speed and accuracy. Users can optimize the performance and efficiency of HVAC components and systems using advanced control features and algorithms.
  • Connectivity: The Alsmart platform can communicate and share data with other devices, systems, and cloud platforms using multiple standard protocols. Users can access and monitor the controller remotely, and leverage the power of digital tools and artificial intelligence to enhance the functionality and value of HVAC solutions.
  • Security: The Alsmart platform provides the highest level of cybersecurity protection by following the latest standards and best practices. Users can trust that the controller and the data are safe from unauthorized access and cyberattacks.

The Alsmart platform is expected to be available in the market by the second quarter of 2024. You can sign up for updates and notifications on the Danfoss website or follow Danfoss on social media.
