Replacement Motor, 24 VAC

The Lennox 10C16 is a 24 VAC damper control module engineered for HVAC zoning systems in commercial and residential applications. This intelligent zone control solution manages up to four separate zones by automatically regulating motorized dampers to direct conditioned airflow only to areas with active demand, optimizing energy efficiency and comfort control across multi-zone installations. Operating on 24 VAC within a 18-30 VAC operating range, the module features a compact footprint measuring 9 1/4 x 6 x 2 inches and weighing approximately 2 lbs, making it suitable for installation in standard equipment cabinets or control panels. The integrated 17A30 power supply provides nominal 12 VDC output (+/-10-14 VDC range) with maximum current draw under 133 mA, while zone dampers are independently powered through a separate transformer (40-75 VA typical), ensuring reliable operation without overloading control circuits. This replacement module is compatible with Lennox iHarmony and Smart Zoning systems, supporting both round and rectangular motorized dampers with spring-open/power-close configurations. The modulating design enables proportional airflow control for enhanced zone balancing and system responsiveness. Ideal for retrofit installations and maintenance applications, the 10C16 provides facility managers and HVAC contractors with a dependable replacement component that maintains system functionality and zoning precision. Compatible with existing Lennox HVAC infrastructure, this module simplifies upgrades and repairs while delivering consistent performance in multi-zone climate control environments.
