Description
Honeywell MARD-16 16″ Round Zone Damper Overview
The Honeywell MARD-16 is a 16-inch round zone damper engineered for reliable airflow control in residential and light commercial HVAC zoning systems. Featuring an integrated 24Vac floating actuator with power open/power closed operation and three-wire control, this damper delivers precise, responsive zone management without the need for a separate actuator assembly.
Key Features
- 16-inch round damper for large-diameter duct applications
- 24Vac floating actuator — compatible with standard zone control panels and thermostats
- Power open / power closed operation for positive blade positioning in both directions
- Three-wire control wiring for straightforward integration with zone panels and controllers
- Integrated actuator design simplifies installation and reduces component count
- Suitable for residential and light commercial HVAC zoning applications
Power Open / Power Closed Advantage
Unlike spring-return dampers, the MARD-16’s power open/power closed actuator actively drives the blade to both the open and closed positions. This ensures positive blade seating in the closed position for maximum zone isolation and eliminates reliance on spring tension over time.
Three-Wire Floating Control
The three-wire floating actuator accepts standard open, close, and common signals from any compatible zone control panel. This wiring configuration allows the damper blade to stop at any intermediate position, enabling proportional airflow control when used with appropriate controllers.
