Io Hvac Controls LD-1208 Rectangular Zone Damper 12x8

Product Description

The IO HVAC CONTROLS LD-1208 is a rectangular 2-position zone damper designed for use in residential and light commercial HVAC zoning systems. It ships with a 3-wire actuator and an integrated LED indicator, allowing technicians to confirm damper position at a glance without additional test equipment. The damper blade opens or closes fully in response to a zone controller signal, directing conditioned air to occupied zones and shutting off flow to unoccupied ones. At 6 pounds, the unit is sized for duct openings measuring 12 inches wide by 8 inches tall. HVAC technicians and sheet metal installers are the primary trades handling this component.

The LD-1208 fits into forced-air duct systems where independent zone temperature control is required. It is suited for new construction zoning installations and retrofit applications where an existing straight duct section can accept a flanged damper insert. The 3-wire actuator configuration is compatible with standard 2-position zone control boards that supply a 24-volt signal to open and a separate signal to close, making wiring straightforward for technicians already familiar with conventional zoning panels.

Key Features

• 2-position operation opens or closes fully for precise zone airflow control
• Integrated LED indicator confirms open or closed actuator position without a meter
• 3-wire actuator wiring matches standard 2-position zone controller outputs
• 12-inch by 8-inch rectangular blade fits common residential trunk-and-branch duct sizes
• Compact actuator package at 6 pounds for easier handling in tight duct chases

Compatibility

Designed as an OEM-style replacement or new-install zone damper for residential and light commercial forced-air duct systems requiring 2-position rectangular dampers with 3-wire actuator control.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified sheet metal installer. Always shut off the air handler or furnace and de-energize the zone control panel before wiring or mounting the damper. The unit should be installed in a straight duct section with adequate clearance around the actuator housing to allow full blade travel. Low-voltage wiring connections must comply with applicable NEC requirements and the zone controller manufacturer's wiring diagram.
