Durable Composite Construction: Resists the high-temperature environment of the furnace flue collector box to prevent premature warping or blade failure

Marvair 92219-2 Economizer Board R-134A 0% linearity for accurate stemThe Marvair 92219 2 Economizer Board is the current direct replacement for the legacy 92219 1, engineered to handle energy management and free cooling cycles in commercial HVAC systems. Designed for high reliability applications, this board utilizes PID control logic to modulate dampers, optimizing the intake of outside air relative to enthalpy and temperature setpoints. By integrating with on board temperature, humidity, and occupancy sensors, the
