The IO HVAC CONTROLS oad-10-mod is a 0-10 VDC modulating motor designed for outdoor air damper applications in commercial HVAC systems. This actuator accepts a 0-10 VDC control signal to drive damper blades to any position within their range, enabling precise outdoor air volume control. It is sized for 10-inch damper assemblies and is installed by licensed HVAC technicians in commercial ventilation and air handling systems where modulating control of outdoor airflow is required.
This modulating damper motor is suited for commercial applications where a building automation system or DDC controller provides a 0-10 VDC analog output signal to regulate outdoor air intake. Typical installations include rooftop units, air handling units, and dedicated outdoor air systems where outdoor air damper control is part of the ventilation strategy.
Designed as an OEM-style modulating damper actuator for 10-inch commercial outdoor air damper assemblies in systems using a 0-10 VDC control signal.
Installation should be performed by a licensed HVAC technician familiar with commercial air handling and building automation systems. De-energize and lock out the unit before mounting or wiring the actuator. Verify the control system output is a true 0-10 VDC analog signal before commissioning. Follow applicable mechanical and electrical codes, including NEC requirements for low-voltage control wiring.
