We confirmed today, thanks to a helpful customer, how another DuroZone damper wires using 3 wires (even though it has 5 terminals).
If your damper motors look like the one shown, wire to SmartZone as shown.
Another DuroZone model… on this model it is reported that some versions TERMINAL 4 (the blue wire shown) goes to CLOSE instead of OPEN.
If your motors looks different than this, see our other posts about damper wiring:
4-Terminal and 8-Terminal Damper Wiring
If the motors you have are not compatible with SmartZone, you still don't have to replace the whole damper. You can replace just the motor (actuator) on just about any standard residential damper with the SmartZone / Belimo motor.
