Phoenix Controls manufactures valves that are commonly found in hospital rooms and labratories to provide reliable space pressurization. In order to stay ahead of the competition Phoenix knew that they needed to update their controls to look and feel as high end as their air handling valves are. Phoenix contracted AndPlus to build a new custom touchscreen control interface that would directly interact with their high precision air handling valves.
AndPlus' first task was to open up communication between the BACnet controller that is onboard on the Air handling unit, and the Android tablet that Phoenix has chosen for their touch screen interface. AndPlus was able to customize an RS232 connector to communicate over twisted pair wiring in order to read and write the points that BACnet communicated over. Once AndPlus was able to establish communication, the Agile Software Development process began in order to build out the specific user stories necessary to deliver a market ready product to Phoenix's customers.
