Ewc Controls END-MA15S Motorized Rectangular Damper

Product Description

The EWC CONTROLS END-MA15S is a motorized rectangular zone damper from the ND Series, designed for precise airflow control in residential and light commercial HVAC zoning systems. This unit pairs an ND Series rectangular damper body with an MA-ND5 actuator, delivering reliable open and close positioning within ducted forced-air systems. It is rated for a 10 by 14 inch duct opening and carries EcoNet compatibility, making it a fit for communicating HVAC systems that use EcoNet-based zoning controls. Installation is handled by licensed HVAC technicians as part of a zone control system build-out or retrofit.

The END-MA15S is suited for residential and light commercial zoning applications where multiple zones require independent temperature control. It fits into rectangular duct sections measuring 10 by 14 inches and integrates with EcoNet-compatible zone control panels and thermostats. Its ND Series construction is intended for use in standard forced-air ducted systems, including those served by gas furnaces, heat pumps, or air handlers.

Key Features

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Disconnect power to the air handler, furnace, or heat pump and de-energize the zone control panel before beginning damper installation or wiring. Follow the zoning system manufacturer wiring diagram for actuator connections and verify EcoNet communication settings after installation. Consult local mechanical codes for duct penetration and damper placement requirements.
