Trane MOD2666 Economizer Logic Mod

The Trane MOD2666 Economizer Logic Mod is an intelligent device specifically designed for Trane air handling units that utilize the RELIATEL control system. Commercial HVAC systems usually have these devices. With a weight of only 0.49 pounds, it is essential for controlling the economizer cycle and maximizing energy use. When the outside air is colder than the internal air that has been conditioned, an economizer uses it to cool the building. By utilizing outside air, the MOD2666 logic mod minimizes the need for mechanical cooling. It does this by calculating the best conditions to use. This results in considerable energy cost savings. By determining when to use free outside cooling to lessen the strain on the mechanical cooling system, the mod essentially functions as a smart switch.
