Io Hvac Controls RM-2414 Rectangular Zone Damper 24x14

Product Description

The IO HVAC CONTROLS RM-2414 is a rectangular zone damper sized at 24 x 14 inches, designed to regulate airflow in zoned HVAC duct systems. It ships with a Belimo actuator configured for 3-wire operation and a 35-second stroke time, giving the actuator controlled, deliberate blade travel suited to residential and light-commercial zoning applications. The damper is installed in the supply or return duct trunk to direct conditioned air to a specific zone based on thermostat demand. HVAC technicians familiar with multi-zone control panels will find the 3-wire hookup straightforward for both power-open and spring-return wiring schemes.

This damper is intended for rectangular duct installations in forced-air zoning systems where independent temperature control is required across multiple areas of a structure. The 24 x 14 inch blade opening suits medium-to-large duct runs commonly found in residential systems with two or more zones or in light-commercial applications. It pairs with a zone control panel that provides the 24-volt signal to drive the Belimo actuator open and closed in response to zone calls. The 35-second actuator travel time helps prevent pressure spikes in the duct system during zone transitions.

Key Features

• 24 x 14 inch rectangular blade opening fits medium-to-large duct runs
• Integrated Belimo actuator with 35-second stroke time for smooth, controlled airflow transitions
• 3-wire actuator configuration supports power-open and spring-return wiring options
• Designed for use with 24-volt zone control panels in forced-air zoning systems
• Suitable for residential and light-commercial multi-zone HVAC installations

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems using 24-volt 3-wire Belimo-style actuators. Verify duct opening dimensions and control panel actuator wiring requirements before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Power down the air handler and zone control panel before making any wiring connections to the actuator. Secure the damper body to the duct using sheet metal screws and seal all edges with approved duct tape or mastic to prevent air bypass. Verify actuator wiring against the zone panel manufacturer wiring diagram before restoring power.
