1. A controller for a heating, ventilating and cooling (HVAC) system, comprising:

  • an input terminal configured to receive feedback data from a pressure sensor associated with a first operating unit of said HVAC system;

    an operation monitor configured to determine if said feedback data corresponds to a predetermined condition for said first operating unit, said predetermined condition being one of a group consisting of;

    a dirty enthalpy wheel and a dirty filter; and

    a processor comprising a system director, in response to the determination that said feedback data corresponds to said predetermined condition, configured to;

    determine a number of occurrences of predetermined conditions associated with said first operating unit;

    determine whether the number of occurrences of predetermined conditions is greater than a first threshold;

    in response to determining that the number of occurrences of predetermined conditions is not greater than the first threshold, operate a fan blower of said HVAC system at a predetermined operating value, said predetermined operating value corresponding to the number of occurrences of predetermined conditions associated with said first operating unit; and

    in response to determining that the number of occurrences of predetermined conditions is greater than the first threshold, turn off the fan blower.
