Smarter Cooling. No Apps. No Updates. Just Natural Cool Air.
Uses thermistors and op-amps to control airflow when it makes sense — no Wi-Fi, no software, no risk (unless you want to).
Pre-cool your home with cooler overnight air. Save money and run the AC less, or not at all.
Works as a window fan, installed wall fan, attic fan, or directly inside your new or existing HVAC.
Reduces peak load strain during hot days. Perfect for California, Nevada, and other high-heat regions.
Can use existing solar tech to store enough power during the day to run all night. Pays for itself in a year.
