Io Hvac Controls RM-1210-BM Zone Damper 12x10 Bottom Mount

Product Description

The IO HVAC CONTROLS RM-1210-BM is a rectangular zone damper designed for zoned HVAC duct systems. It features a bottom-mount configuration and ships with a 3-wire Belimo actuator rated for a 35-second stroke time. The damper controls airflow through a 12-inch by 10-inch duct opening, allowing zone controllers to modulate or shut off conditioned air to individual zones. Licensed HVAC technicians install this damper during new zoning installations or as a direct replacement in existing systems. The bottom-mount actuator position suits applications where top or side access is restricted.

This damper is used in residential and light commercial forced-air zoning applications where independent temperature control is required for separate areas or rooms. It fits into standard rectangular duct runs and pairs with compatible zone control panels and thermostats. The 3-wire Belimo actuator provides spring-return operation, meaning the damper returns to a fail-safe position on loss of power, which is standard practice for zoning system design.

Key Features

• 12-inch by 10-inch rectangular duct opening for direct duct integration
• Bottom-mount actuator positioning for restricted-access installations
• Belimo actuator with 35-second stroke time for controlled airflow modulation
• 3-wire actuator wiring for compatibility with standard zone control panels
• Spring-return fail-safe operation on power loss

Compatibility

Designed as an OEM-style replacement for rectangular zone damper applications in residential and light commercial forced-air zoning systems requiring a 12-inch by 10-inch bottom-mount damper with a 3-wire Belimo actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control system before beginning work. Secure the damper into the duct opening per the manufacturer fit guidelines and route low-voltage wiring to the zone control panel following NEC low-voltage wiring requirements. Verify actuator stroke direction and fail-safe position before returning the system to service.
