Io Hvac Controls HD-0606-PO Zone Damper 6x6 Powered Open

Product Description

The IO HVAC CONTROLS HD-0606-PO is a two-position zone damper designed for use in forced-air HVAC zoning systems. It operates on a powered-open principle, meaning an actuator drives the blade to the open position and spring return closes it when power is removed. This fail-safe behavior is critical in zoning applications where an unpowered zone must default to closed to protect equipment and maintain pressure balance. The damper fits a 6-inch by 6-inch duct opening and is installed by licensed HVAC technicians integrating multi-zone control into residential or light commercial ducted air systems.

This damper is suited for residential and light commercial forced-air zoning installations where individual room or area control is required. It is placed in branch duct runs and wired to a zone control board or thermostat system that sequences zone calls. The powered-open, spring-return design makes it appropriate for systems where defaulting to a closed position on power loss is the correct fail-safe behavior, such as in smaller branch zones that should not receive airflow during standby.

Key Features

• Powered-open, spring-return operation defaults to closed position on loss of power
• Nominal 6 x 6 inch duct size fits standard rectangular branch duct openings
• Two-position actuator provides simple open or closed blade control with no modulating signal required
• Compact package dimensions allow installation in tight plenum and duct cavities
• Compatible with standard low-voltage zone control boards used in residential zoning systems

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential and light commercial forced-air zoning systems using 6 x 6 inch rectangular duct branch connections.

Installation Notes

Installation should be performed by a qualified HVAC technician familiar with zoning system wiring and ductwork. Disconnect power to the zone control panel before wiring the actuator leads. Ensure the damper is oriented according to airflow direction marked on the housing, and verify the blade moves freely through full travel before sealing the duct connection. Low-voltage wiring should comply with NEC requirements for Class 2 circuits.
