Which Motorized Damper to use?

Post by Wright42 »

Looks like there are two main types of round Dampers:
URD - powered both ways with open/close LED
RSD - powered one way, spring back

What determines which one to use?
If I use the NCM300 control panel, is one perferred over the other?

Thanks,

Jim,

The URD (Power Open/Power Close) dampers are preferred in zoning applications, while the RSD (Spring Return) Dampers are preferred in fresh air intake applications. I would recommend for you to use the URD style dampers.
