Nordyne 558870 Modulating Downflow Economizer w/filter (does not require filter kit) 2 - 5 Ton
The Economizer is designed to slide into the air conditioning unit through the return access panel. All of the controls are wired and mounted and all of the damper linkage is installed. No field linkage adjustments are required. Wiring harness between Economizer and unit is provided. The control systems feature the new Honeywell solid state control actuators and enthalpy control. The option for differential (dual) enthalpy is also available. This will allow the use of either return air or outside air (whichever is coolest) to cool the space.
