DuroZone RD-Series Dampers to Zone Control Panel Hookups
All other Panels: The DuroZone RD-Series dampers can be controlled by hooking 24 Common to damper terminal 1, 24vac hot to terminal 2, and then switching 24vac hot to terminal 4: Power to terminal 4 causes the damper to open: removing power causes the damper to close. For control by most thermostats, hook damper terminal 1 to 24vac common (C), damper terminal 2 to 24vac hot (R), then damper terminal 4 to thermostat Y and W (jumper W and W stat terminals together.)
