A furnace is a device used to control high temperature heating. A residential furnace is a device that heats air and passes it (via ductwork) to the space where the air is being heated. In this reference design, Renesas provides solutions for residential furnaces that are equipped with a moving blower to move air via the duct system. The reference design also includes an air quality sensor that can monitor conditions in rooms or ducts.

System Benefits

  • High integration 32-bit microcontroller (MCU) with 12-bit A/D for better precision and compact control
  • Features a galvanically isolated high-speed differential bus transceiver, which is designed for bidirectional data communication on balanced transmission lines 
  • Indoor air quality sensor platform for total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ)
