Io Hvac Controls ld-2008-bm Zone Damper 20x8 in 3 Wire

Product Description

The IO HVAC CONTROLS ld-2008-bm is a 2-position rectangular zone damper designed for use in forced-air HVAC zoning systems. Measuring 20 inches by 8 inches, it accepts a 3-wire actuator and features a bottom-mount configuration for straightforward installation in tight duct runs. The integrated LED indicator provides a visible status signal so technicians can confirm damper position without removing access panels. This damper is installed by licensed HVAC contractors working on residential zoning applications where independent temperature control is required across multiple zones.

The ld-2008-bm is suited for residential forced-air zoning installations where rectangular duct sections require motorized zone control. The bottom-mount actuator orientation accommodates duct configurations where side or top access is restricted. The 2-position operation means the damper moves fully open or fully closed in response to zone controller signals, making it a reliable fit for standard 24-volt zoning panel setups commonly found in residential split systems and air handler applications.

Key Features

• 20 x 8 inch rectangular duct size fits standard residential duct openings
• 2-position operation provides fully open or fully closed damper control
• 3-wire actuator wiring compatible with standard 24-volt zone control panels
• Bottom-mount actuator orientation for installations with limited top or side clearance
• Integrated LED indicator confirms damper position at a glance

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential forced-air zoning systems using rectangular duct sections sized 20 inches by 8 inches.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zone control panel before beginning any wiring or duct work. Confirm duct dimensions and actuator clearance on the bottom side of the duct run before mounting. Follow applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, when connecting the 3-wire actuator harness to the zone controller.
