Io Hvac Controls RM-2214-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS RM-2214-BM is a rectangular zone damper designed for zoned HVAC duct systems requiring precise airflow control. Measuring 22 inches by 14 inches with a bottom-mount configuration, this damper pairs with a 35-second Belimo actuator using a 3-wire control setup. The 3-wire actuator allows for both open and close power signals, giving zone controllers accurate positioning feedback and reliable operation. Weighing 11.73 pounds, the unit is a fully assembled, installation-ready assembly suited for residential and light commercial zoning applications. HVAC technicians install this as part of a multi-zone forced-air system managed by a compatible zone control panel.

The RM-2214-BM fits into rectangular duct runs where bottom-mount actuator placement is required by duct layout or clearance constraints. It is used in forced-air zoning systems where individual zones must be opened or closed independently in response to thermostat calls. The 22-inch by 14-inch duct opening size targets mid-to-large residential trunk or branch ducts. The bottom-mount design keeps the actuator accessible for servicing without requiring duct disassembly. This damper is appropriate for new zoning installations and direct replacements in existing Rheem-compatible zoned systems.

Key Features

• 22 x 14 inch rectangular duct opening for mid-to-large residential duct applications
• Bottom-mount actuator placement for accessible servicing in tight installations
• 35-second Belimo actuator provides controlled, reliable open and close travel speed
• 3-wire control wiring supports powered open and powered close signals from zone panels
• Factory-assembled unit arrives ready for duct installation

Compatibility

Designed as an OEM-style replacement zone damper compatible with Rheem rectangular duct zoning systems requiring a 22 x 14 inch bottom-mount damper with a 3-wire Belimo actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Shut down the air handler and de-energize the zone control panel before connecting wiring or mounting the damper in the duct. The 3-wire actuator requires correct identification of the common, open, and close terminals at the zone panel before energizing. Follow local mechanical and electrical codes, including applicable sections of the IMC and NEC, when running low-voltage control wiring to the actuator.
