View Full Version : Lennox economizer

Got a question to ponder. In a new Lennox "L" class unit, is it possible for the economizer dampers to be open, beyond minimum position, AND have a call for second stage cool? Assume that outside air is acceptable to the enthalpy sensor.

Yes it is possible after a call for economizer if the space connot satisfy then second stage (compressors) come on. The time it takes to time out is a configurable point in the L series. You can increase or decrease the delay.
