Io Hvac Controls RM-2816 Rectangular Zone Damper 28x16

Product Description

The IO HVAC CONTROLS RM-2816 is a rectangular zone damper designed for use in ducted HVAC zoning systems. It ships with a 35-second Belimo actuator wired in a 3-wire configuration, allowing the damper to open and close on command from a zone control board. At 28 inches wide by 16 inches tall, this unit fits mid-to-large trunk line applications where precise airflow control is required. The 3-wire actuator setup supports both power-open and power-close operation, giving the system reliable positioning across heating and cooling cycles. Licensed HVAC technicians and zoning system installers are the primary trade for this product.

This damper is suited for residential and light commercial forced-air zoning installations. It mounts inline in rectangular ductwork as part of a multi-zone HVAC system, directing conditioned air to specific zones based on thermostat demand. The Belimo actuator is a widely specified brand in commercial and residential zoning, and its 35-second travel time is compatible with standard zone control board timing requirements. Typical installations include systems using a central air handler with multiple zones served by rectangular supply trunks.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with duct zoning systems and low-voltage control wiring. Shut down the air handler and de-energize all control circuits before cutting into ductwork or connecting actuator wiring. Secure the damper in the duct with sheet metal screws and seal all seams per local mechanical code. Verify actuator travel direction and zone board wiring polarity before restoring power to the system.
