New Luxaire 2 stage furnace

The install manual should say how to wire a single stage condenser - Y1 and Y2 may have to be jumpered as Y1 call is always present when power is applied to Y2 by t-stat in a 2-stage setup.

Also set the dip switches to match the size of a/c. 350 to 450 cfm per ton. (lower than 400 cfm per ton improves dehumidification at the expense of capacity/efficiency, higher cfm does the opposite)

The factory setting is usually the maximum - 1200, 1600 or 2000 cfm, too much airflow for smaller units.

the install manual just shows a wire to Y2 for single stage condenser, no jumper.

That is the way I see it, but this is not something that I do every day, so I wanted to ask the question.
