Lennox 11G24 Economizer Control

The Lennox 11G24 Economizer Control Module that operates compatible Lennox HVAC systems and controls the amount of fresh air intake. It operates by deliberately drawing cooler air from the outside to be combined with air from the indoors that has already been conditioned, possibly decreasing the amount of work your system has to do. It can mean reduced energy use and increased general system effectiveness for air conditioning, ventilation, and heating. This model is universal and works on both 50Hz and 60Hz electrical systems.
