New Danfoss series programmable HVAC controller

DENMARK: The Alsmart universal controller is the latest generation of programmable controllers for the HVAC market from Danfoss. 

It is said to combine flexible and advanced control features, multiple communication options, the highest levels of cybersecurity protection, and powerful and easy to use programming tools. 

“Alsmart is an enabler allowing manufacturers and end users to deliver sustainable solutions with the highest efficiency while driving to reduce energy consumption and CO2 emissions in green buildings,” Danfoss said. 

It is said to be designed with the latest processing power and memory to meet the most demanding applications, making the programming of applications and algorithms easy, efficient, and fast by using standard programming languages (IEC 61131-3). 

Through a patented side-by-side connector method, users can add additional input and output modules that allow optimum and future flexibility in their application. This is said to provide the ultimate in flexibility when controlling HVAC components like valves, sensors, compressors, energy meters, switches and other devices. 

Communication is said to be a key design priority, starting from a ground-up design approach that ensures the highest cybersecurity protection adhering to stringent IEC 62443-4-2 cybersecurity standards. 

Communication flexibility allows connections through a wide variety of standard protocols including BacNet, CanBus, Modbus, SNMP, HTTPS, and MQTT/S. 

Alsmart supports multiple user interface and display options beginning with a patented snap-on display which can be easily plugged into the control and locked by a magnet. The display unit can also be used in the field or production line to download updated firmware to multiple different units. Through its multiple communication options, developers can use a variety of different user interfaces including more advanced HMI units or by connecting into a BMS. 

“As the HVAC industry works diligently to help building owners achieve their targets relative to climate goals and climate related regulations, it is critical that the components work together in a smarter way whether in a data centre chiller, rooftop HVAC unit, heat pump or DOAS system,” said Michael Kellerman, Danfoss’ director of EC&S development. 

“Alsmart allows that to happen as the brain of these systems and subsystems. Furthermore, the communication options in Alsmart allows it to easily communicate with Building Management Systems (BMS) or directly to IOT Clouds of the building owner, OEM manufacturer or building maintenance companies.”
