The Innovair™ ventilation controller is based on demand control ventilation, a method of control using a carbon dioxide sensor to monitor the actual occupancy of a space. By following occupancy patterns rather than using fixed ventilation rates, the unit ensures indoor air quality while minimizing energy costs by avoiding over-ventilation, says the company. The controller can be duct or wall mounted. Its keypad and digital display allow for simple range and elevation adjustments, the company says.
