Io Hvac Controls ld-1208 Zone Damper 12x8 in 3 Wire

Product Description

The IO HVAC CONTROLS ld-1208 is a rectangular two-position zone damper designed for residential forced-air HVAC zoning systems. Built in a 12-inch by 8-inch duct size, it uses a three-wire actuator to drive the blade between fully open and fully closed positions. An integrated LED indicator allows technicians to confirm actuator status at a glance without additional test equipment. Licensed HVAC technicians install this damper as part of a zoned comfort system controlled by a compatible zone control panel.

The ld-1208 is suited for residential zoning applications where a single air handler or furnace serves multiple zones through a branched duct layout. The rectangular form factor fits standard rectangular duct trunk lines and branch runs. The three-wire wiring scheme supports spring-return or powered-open and powered-close operation depending on control panel configuration. This damper is sized for common residential duct runs where airflow must be modulated by zone demand.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler or furnace and de-energize the zone control panel before wiring or mounting the damper. Verify duct dimensions before installation to confirm a proper fit in the rectangular duct opening. Follow the control panel manufacturer wiring diagram for correct three-wire actuator terminal connections and observe applicable mechanical and electrical codes.
