The Approach

NexRev installs variable frequency drives (VFD) that are commonly used as aftermarket additions to commercial HVAC units. These VFDs allow the HVAC units to run at reduced power levels while still providing appropriate output to maintain a building temperature while saving power and money for large commercial building owners. In order to expand their reach, NexRev engaged with dealer partners to install and program VFD units. In order to ensure that they were programmed with appropriate settings and done right the first time, NexRev needed to automate more of the process and provide quality control. They engaged with AndPlus to build a piece of software to do just that. 

AndPlus' first step was to build an MVP piece of software that simply took in manually-entered readings from various sensors on the unit and gave the installer tech input values for the unit. This basic, manual process showed that the complex algorithms use to program the VFDs could be translated easily into a simple-to-use piece of software.

How we architect custom apps

It all starts with the AndPlus Technical Architects. A team of Senior Engineers that map out every possible tech stack for your project prior to kickoff. The right tech, every time.

The Result:

Once the initial hurdle of an MVP was cleared, the next phase was to add automatic intake of the sensor readings and an automated push to the VFD through a wired connection. Soon, the software would gather relevant data, crunch numbers, and program the drives automatically with little user interaction. AndPlus also added the requirement for dealer partners to submit photos of the site to prove that the area was left clean and that the job was completed appropriately — even though dealer partners were doing the installation, NexRev's name was still "on the box."

The DCT is now used nationwide for large commercial clients, and has recently expanded internationally. The iterative buildout and integration of complex devices in one software package are just a few more ways that AndPlus drives innovation for our clients.

AndPlus understands the communication between building level devices and mobile devices and this experience allowed them to concentrate more on the UI functions of the project. They have built a custom BACnet MS/TP communication stack for our products and are looking at branching to other communication protocols to meet our market needs. AndPlus continues to drive our product management to excellence, often suggesting more meaningful approaches to complete a task, and offering feedback on UI and Human Interface based on their knowledge from past projects.
