Honeywell M847D Replacement Damper Motor RZ3-1M

Upgrade your HVAC system with the Retrozone RZ3-1M 2-Wire Spring Return Damper Actuator, a direct replacement for Honeywell’s M847D series motors. Engineered for seamless compatibility with ZD and ARD dampers—including models like M847D1004 and M847D1012—this durable actuator offers a hassle-free, drop-in installation. Perfect for both normally open and closed systems, it also serves as a reliable alternative to Hansen 135-6 and other 2-wire spring return motors.

Built for longevity, the RZ3-1M features all-metal, precision gears—twice as wide as Honeywell’s OEM plastic alternatives—to eliminate common failure points. For added convenience, each kit includes a 24VAC test light and a troubleshooting guide, ensuring quick diagnostics and reliable performance. Operates at 24VAC ±10%, 60Hz, and 0.36A for smooth, efficient operation.
