Description
The Honeywell MARD-14 is a 14-inch round zone damper engineered for precise, reliable airflow control in residential and light commercial HVAC zoning systems. Featuring a 24Vac power open/power closed operation with a three-wire floating actuator, this damper delivers positive, motorized control in both directions — ensuring the damper reaches and holds its commanded position without relying on spring return.
Key Features
- 14-inch round damper for standard ductwork applications
- 24Vac operating voltage — compatible with standard zone control boards and thermostats
- Power open / power closed operation for positive two-directional control
- Three-wire floating actuator design for reliable, accurate positioning
- Motorized actuator eliminates spring-return dependency
- Suitable for residential and light commercial HVAC zoning systems
Why Choose the MARD-14?
The power open/power closed configuration means the actuator actively drives the damper blade in both directions, providing more reliable and consistent zone control compared to spring-return alternatives. The floating three-wire control interface makes integration with most zoning panels and controllers straightforward, reducing installation time and complexity.
