Io Hvac Controls RM-2012 Rectangular Zone Damper 20x12 in

Product Description

The IO HVAC CONTROLS RM-2012 is a rectangular zone damper designed for use in residential and light commercial zoning systems. It ships with a 3-wire Belimo actuator that opens and closes in approximately 35 seconds, providing reliable airflow control across individual zones. The damper measures 20 x 12 inches, making it a standard fit for rectangular trunk or branch ductwork. Licensed HVAC technicians install this unit as part of a multi-zone forced-air system, typically in conjunction with a zone control board and individual zone thermostats.

This damper is suited for zoned HVAC applications where independent temperature control is required across multiple areas of a structure. The 20 x 12 inch rectangular form factor fits standard duct openings of that size in both residential new construction and retrofit installations. The included Belimo actuator integrates with common 3-wire zone control systems, accepting a low-voltage signal to modulate airflow on demand. It is appropriate for use in supply or return air duct branches where controlled zone isolation is required.

Key Features

• 20 x 12 inch rectangular duct size for standard trunk and branch duct openings
• Includes factory-mounted 3-wire Belimo actuator for direct integration with zone control boards
• 35-second actuator cycle time provides controlled, gradual airflow adjustment
• Low-voltage 3-wire wiring configuration compatible with standard zoning control systems
• Designed for residential and light commercial forced-air zoning applications

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct systems requiring a 20 x 12 inch damper with a 3-wire low-voltage Belimo actuator. Listed in the Rheem zone damper product line.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zone control board before wiring the actuator. The 3-wire actuator connects to the zone control board per the board manufacturer wiring diagram. Ensure the damper blade moves freely and the duct opening is properly sized before securing the unit in the ductwork.
