Lennox 21Z09 Sensor Kit 320788-704 5 VA nominal to minimizeThe Lennox 21Z09 Enthalpy Sensor Kit (also identified as 603364 35) is a critical diagnostic and control component for commercial HVAC rooftop units. Operating as a high precision dual sensing device, this enthalpy sensor replacement monitors both sensible temperature and relative humidity to determine the total heat content of the air. This data is essential for economizer air side control, allowing the system to utilize outdoor air for free cooling
