About this item

  • The Retrozone RZ3-1M 24 vac 2 wire spring return damper motors are designed as drop in replacements for Honeywell's M847D series motors on popular ZD and ARD dampers, including M847D1004, M847D1012, and other M847D series motors.
  • These motors also replace most Honeywell 2 wire spring return motors, as well as many other brands and work with normally open and normally closed installations.
  • These motors are also replacements for the Hansen 135-6 motor, as well as other brands with the same footprint.
  • Our all metal gears and precision engineering get rid 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 the gear comparison in the product photos.
  • Don't be left in the dark when your new motor, damper, transformer, or thermostat fail to work. Our handy 24 volt test light and troubleshooting guide, included with motor, allow you to test power to your motor and perform a complete diagnostic evaluation of your zoning system when used with our 2 page troubleshooting guide.
  • Voltage: 24 VAC +/- 10%, 60 Hz, 0.36A
  • Torque Rating: Power open 32 in. oz./spring close 32 in. oz. - torque is consistently delivered throughout the full 90º rotational operating range to open and close the damper, irrespective of whether the actuator is operating in Power Advance Mode (energized) or Spring Return Mode (de-energized).

    Outstanding!
    AC company wanted to charge me $350 for this. Do yourself a favor and do it yourself. This piece replaced my burnt out Honeywell motor. Took about 10min to replace and test. I know nothing about AC service either. This part and YouTube saved me a little chunk of cash!
