I really wanted this to work, but it is not compatible with Trol-A-Temp ZD Zone Dampers. The shaft is totally wrong, and can not be modified to work. Unfortunately, the damper actuators that do work with Trol-A-Temp are just not designed to last for more than a couple years. This Honeywell unit has a much stronger actuator motor which makes me think it should last much longer.

I've not had other brands of damper motors last very long. I was hopeful that by spending more and going with an official Honeywell I would finally have something that would last. This one jammed in the closed position after only 10 months of normal service. As others have said virtually impossible to make a warranty claim. I disassembled it and found that the gear train was jammed and the spring was not strong enough to open the damper. When I pried the gear with a screwdriver it did unjam and open. but it's obviously defective

Direct Replacement for my old M847 Honeywell actuator. Total install took roughly an hour, including testing time. Be sure to mark the damper position to know where it is fully open before connecting wiring. My damper rotated during install and I had to reposition it and reinstall. Not a big issue, but definitely mark the position first.
