    What Brand/Model of system do you have?

    if it's a Trane, just make sure the dip switches are set up, and jumper wire is used.. No other control is needed.

    it is a goodman, gmv90905dxa furnace, clq42 a/c. the guy said you get alot of product for the money. i tried moving those switches(please don t tell me i need a professional to change the settings, its only a slight change in airflow) but i don t get the 30 second pre run or the 7.5 minute reduced speed

    Goodman had a programming error on some of the VS boards, call your contractor back to fix the problem.
