Lennox 11G27 Enthalpy Sensor 322055-301 Draft is adjusted via theThe Lennox 11G27 Enthalpy Sensor is a critical component for optimizing demand control ventilation (DCV) and economizer performance in Lennox commercial HVAC systems. This solid state sensor monitors both sensible and latent heat to determine the energy content of outside air, allowing the controller to modulate economizer dampers for maximum efficiency. Designed for precise integration with Lennox rooftop units (RTU), the 11G27 ensures that "free
