Io Hvac Controls MD-1612-BM Zone Damper 16x12 in Bottom Mount

Product Description

The IO HVAC CONTROLS MD-1612-BM is a rectangular two-position zone damper sized at 16 inches wide by 12 inches tall, factory-fitted with a Belimo three-wire actuator mounted on the bottom of the frame. Zone dampers control airflow to individual zones in a ducted HVAC system, opening or closing on a call from the zone controller or thermostat. The Belimo actuator provides reliable spring-return or power-open operation depending on control wiring configuration. This unit is intended for installation by licensed HVAC technicians in residential or light-commercial zoning systems.

The MD-1612-BM is suited for rectangular duct zoning applications in forced-air heating and cooling systems. The 16 x 12 inch duct opening fits a common trunk or branch duct size in both new construction and retrofit zoning projects. The bottom-mount actuator position is useful in installations where side or top access is restricted. HVAC technicians typically deploy this damper in multi-zone systems paired with a zone control panel and low-voltage thermostats.

Installation Notes

Installation should be performed by a licensed HVAC technician. De-energize the air handler and zone control panel before installing or wiring the damper. Secure the damper into the duct using sheet metal screws and seal joints with approved foil tape or mastic per local mechanical code requirements. Verify actuator wiring matches the zone control board terminal designations before restoring power.
