Overview

The heating, ventilation and air conditioning (HVAC) sector is constantly evolving and new technologies are being introduced to enhance effectiveness, decrease environmental impact, and provide superior customer service. The RealityCheck™ HVAC solution is tailored to address these requirements in response to new and more stringent environmental regulations, as well as a growing call for automation.

The solution is equipped with a set of AI models that can detect various conditions on your HVAC unit using vibration, temperature, and electrical signals to predict a wide range of anomalies, faults, and operating conditions. By combining machine learning and edge processing, Renesas MCUs allow your HVAC system to operate more efficiently while reducing environmental impact and improving overall user satisfaction.

RealityCheck HVAC is a comprehensive framework that includes a hardware and firmware reference design, a set of pre-trained ML models ready to leverage for your product design, and a clearly outlined process for model training, customization, and field testing to meet your specific product requirements.
