Due to the high failure rate of Honeywell and Trol A Temp MARD series of motors, we are offering a drop-in replacement motor with a much more robust gear train.  



Theses 24vac motors by Retrozone are drop-in replacements for most Honeywell 2 wire normally open, power to close spring return motors.  Check our Gears in the picture!  Our all metal gears and precision engineering get rid of the of the failure prone thin metal or plastic OEM gears from Honeywell.  Our gears are twice as wide as the new "improved" Honeywell plastic covered motors.  See for yourself in our comparison motor photos. We have also included photos of the motors that ours replaces.  These motors are made for dampers that are normally open, as used with Honeywell and Trol a Temp zone control systems. 


Picture 1  and 2 shows the heavy duty replacement motor you will receive. 

Picture 3 shows our wide, heavy duty metal gear train to end gear failure. 

Picture 4 and 5 show our wide metal gear compared to thin failure prone Honeywell OEM gear. 

Picture 6, 7, and 8 show some of the motors the Retrozone RZ3-1 will replace. 


These motors offer:

Less Cost

Better Quality

Full 1 Year Warranty

 

Features and Benefits


*Works as a replacement for Honeywell M847D series motors on popular ZD and ARD dampers, including M847D1004 and M847D1012 motors and other M847D series.

*Torque is consistently delivered throughout the full 90 degree rotational operating range to open and close the damper, and irrespective of whether the actuator is operating in Power Advance Mode (energized) or Spring Return Mode (de-energized).

*The energized actuator may be stalled at any angular position and remain energized indefinitely.

*When de-energized, the actuator consistently returns the damper shaft to home position, whether or not the starting spring return position is a full 90 degrees or any intermediate position.

*Extremely reliable.  Statistical life reliability exceeds 120,000 cycles at 90% reliability and 100% confidence with no decay in delivery torque over life of the actuator.

*Very quiet operation typically 40dB, or less at 3 feet.
