Upgrade Your Damper System with Confidence Stop dealing with the recurring issues of spring return motors. Our Belimo to replacement for Honeywell Retrofit Kit is designed to seamlessly replace and fit the Honeywell M847D, M847D1004, and M847D1012 motors with the commercial-grade Belimo LMB24-3-T 3-wire actuator — one of the most trusted names in damper control worldwide. This comprehensive retrofit kit includes a precision-engineered steel shaft adapter and all necessary mounting hardware for quick and secure installation on your existing damper. Engineered for compatibility, it serves as a direct replacement for Honeywell M847D series motors commonly found on ZD and ARD dampers, as well as Trol a Temp MSR, RDMH, and many other systems. Why Upgrade? Traditional 2-wire spring return dampers consume power continuously to counteract the return spring, resulting in excessive heat buildup, wasted energy, and premature failure. In contrast, this Belimo actuator offers higher reliability and energy efficiency — without the heat or wear.
