1. In a temperature control system for maintaining the temperature of fluid in a conditioned space at a predetermined set point temperature, the method comprising the steps of:

  • (a) operating the temperature control system in a first operating mode;

    (b) sensing the temperature of the conditioned space fluid;

    (c) calculating the Integral Error of the temperature of the conditioned space fluid; and

    (d) if the Integral Error equals or exceeds a predetermined Integral Error threshold value for the first operating mode, switching the unit to a second operating mode.
