The IO HVAC CONTROLS ld-1806 is a rectangular two-position zone damper designed for residential ducted HVAC zoning systems. The unit measures 18 inches by 6 inches and uses a three-wire actuator to drive the blade between fully open and fully closed positions. An onboard LED indicator provides a quick visual reference of damper state without requiring a meter or test light. Licensed HVAC technicians install this damper inline within rectangular ductwork as part of a zoned forced-air system controlled by a compatible zone control board.
The ld-1806 is suited for residential zoning applications where individual rooms or zones require independent temperature control. It fits within standard 18-inch by 6-inch rectangular duct runs and integrates with three-wire zone control wiring schemes common in residential multi-zone forced-air heating and cooling systems. This damper is appropriate for new construction zone installations and retrofit zoning projects alike.
Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems requiring an 18-inch by 6-inch two-position damper with a three-wire actuator.
Installation should be performed by a licensed HVAC technician familiar with residential zoning systems. Power down the air handler and zone control board before wiring or inserting the damper into the duct. Secure the damper to the duct using sheet metal screws and seal edges with approved HVAC foil tape to prevent bypass air leakage. Verify actuator wiring against the zone control board manufacturer wiring diagram before restoring power.
