The FIAECON003A is a dry bulb economizer designed for 15-25 ton Precedent packaged rooftop units, enabling efficient outside air use for cooling. This economizer allows for 0-100% modulation of outside air, reducing the need for mechanical cooling when outdoor conditions are suitable, thus saving energy. Compatible with American Standard and Trane units, it integrates with Symbio 700 controllers for advanced control. Constructed for durability, this economizer is ideal for commercial applications where energy efficiency and ventilation are priorities.
