Automatic Ventilation Control with Broan-Nutone's Overture: Customizable, Modular Fresh Air System

Corbett Lunsford

Places are different, homes are different, families are different. There IS NO SINGLE SOLUTION for ventilation, and that's the way it's likely to stay- so the more modular, customizable components we have access to, the better.

In addition to having some of the most advanced ERVs in the world (stay tuned for more on that), Broan has now made customized, modular ventilation systems much more practical with this lineup of Overture controls: room sensor, wall control, and smart plug- all linked to the algorithms in an app.

The Overture system can control exhaust fans, supply fans, make up air dampers, and ERVs/HRVs- we hope they will continue to push forward into controlling air handlers, dehumidifiers, humidifiers, and more. Learn more about this system and start brainstorming what you might do with it at: https://Overture.Broan-Nutone.com
