Zonefirst® RDSC06ZF

The RDSC is a 24VAC motorized round spring return damper that powers open and spring returns closed. This is the same damper as the RDS, but it is factory shipped in the normally closed position versus the normally open RDS. The RDSC and RDS dampers can be field converted from normally closed to open, and vice versa. The normally closed operation is ideal when the dampers are used to control outdoor air.
