A RetroZone Exclusive!

Quality Hansen Synchron(tm) brand 3 wire motor upgrade for your two wire spring return dampers. 

Gets rid of power-robbing, failure-prone and hot spring return motors!

*Replaces the higher failure rate Honeywell, ARD, Jackson HD and D XX series, Zone First, RobertShaw, EWC, Trol-A-Temp, RDMZ and ARD, Hansen, Synchron, and other motors using this common footprint.

Note: This motor requires 3 wires from your current zone control panel to the motor. All Honeywell, Trol A Temp, EWC, Durozone, Ecojay, and most zone panels offer a 3 wire damper output. Using this motor is as simple as connecting the third wire from the unused damper terminal, often marked NO, M4, or Norm open. Email us with any questions. 

The same footprint used by almost all brands. Replaces many 2 wire spring return motors with a "common footprint" design, with 1.33 or 1 and 5/16 inch center shaft to shaft spacing. Some "new construction" type panels only offer a 2 wire output, contact us by email or phone for an interface relay.

Why use this 3 wire, power open, power close motor?

 A 2 wire spring return damper must pull 8 to 10 watts of power the entire time they are energized to keep the damper closed, since the spring is always trying to pull it open. Worse, the spring puts unnecessary stress on the gears, which often fail on these motors.

Synchron RZ135-7 motor de-powers itself when fully open or closed, using less power over-all, never gets hot, and there is no spring to put stress on the gear train, so the lifespan of the motor tends to be longer.

Green and Red lights make set up and use a snap.

Three Wires:

White= common or M1

Red = Open or M4

Green= Close or M6

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

 M847D1004 and M847D1012 motors and other M847D series. 

    * This also replaces the Hansen 135-6 motor, as well as other brands with the same footprint.

* Also works on these models:

• Jackson HD series
• Jackson D XX series
• Zonefirst ZDS 
• EWC URD
• Robert Shaw DAR
• Trol a temp RDMZ RDMH MARD
• Hansen
• And many others 

**Motors may also be shipped with a brushed aluminum cover or a plastic cover as shown; otherwise are identical.

These motors offer:

• Less Cost
• Better Quality
• Full 1 Year Warranty

Features and Benefits:

• Uses power only while moving
• 30 seconds run time
• Motor never gets hot.
• Torque is consistently delivered throughout the full 90 degree rotational operating range to open and close the damper. Damper must travel full 90 degrees to de-power.
• 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.

Will not work on Carrier Infinity and VVT systems using a modulated motor. See our "Carrier Infinity" motors.

In addition to this motor, we also offer our BH KIT1 that comes with a Belimo, commercial grade, three wire motor
