IO HVAC Controls RD-XX Series Retro Damper
RD-XX SERIES RETRO DAMPERTM
The RD-XX Series Retro Dampers are devices that can be used with most zone control panels that have the ability to directly power a 3-wire actuator. Each Retro Damper is rated at 24Vac, 2VA. The zone control system transformer must be sized to handle the total VA of all dampers. In some applications, additional dampers may require a relay and separate transformer.
PRODUCT INSTALLATION AND WIRING INSTRUCTIONS
Follow the steps below to install and wire the RD-XX Series Retro Damper:
- Each RD-XX Retro Damper is supplied with a self-adhesive template that is applied to the round section of duct where the damper is to be installed. The template should run parallel to the duct work.
- Use the template to drill two 1″ holes. Cut out the area between the two holes.
- Drill four 1/8″ holes in corners to mount the damper to existing duct work.
- The damper blade must be parallel to the damper frame. Press in on the gear release tab to manually position the blade.
- Slide the damper into the duct and secure it with the four supplied mounting screws.
- Attach the three wires to the correct terminals:
- 1 = Common
- 2 = Powered Close
- 3 = Powered Open
