Abstract
An air conditioning system in which system operation is interrupted when the space to be conditioned is unoccupied: when the outside air is of sufficiently low enthalpy the system cooler and damper controls are disabled and outside air is used for cooling, unless its enthalpy or temperature is indeed too low, when normal system operation is reestablished.
