1. A temperature control apparatus which comprises, in combination, an outdoor temperature detector for detecting the outdoor temperature of the outside of a space to be air-conditioned, an indoor temperature detector for detecting the indoor temperature in the space to be air-conditioned, a storage device for storing a plurality of desired indoor temperatures each of which is expressed by a linear function of the outdoor temperature and for storing a plurality of desired indoor temperatures each comprised of a fixed value, a comparing means operatively connected to and responsive to said indoor and outdoor temperature detectors and said storage device for comparing the detected indoor temperature with a selected one of said desired indoor temperatures, and a control device operatively connected to and responsive to said comparing means for controlling the operation of an air-conditioning apparatus;

  • wherein said storage device stores the linear function of (y=ax+b), wherein a represents a coefficient and b represents a constant and x represents the outdoor temperature and y represents the desired indoor temperature, said coefficient and constant being varied by manipulating an indoor temperature adjustment to any one of a plurality of adjustment notches;

    and wherein means are provided for switching between any one of said plurality of desired indoor temperatures comprised of a fixed value, corresponding to the indoor temperature adjustment notches, and any one of said plurality of desired indoor temperature expressed by the linear function and corresponding to the indoor temperature adjustment notches.
