<p>An adaptive control system uses a controller for controlling an air temperature treatment apparatus 2 at a reduced energy consuming level during periods of non-occupancy of a building 4 and for energizing the air treatment apparatus before occupancy so that a desired internal building temperature is reached by a time of occupancy. The controller includes a temperature sensor 8 for sensing an environmental temperature within the building, a control timer TMR1 responsive to the actual time-of-day for initiating the start of a pre-occupancy control cycle for the temperature treatment apparatus at a first predetermined real time, an adjustable timer TMR2 for defining a second predetermined time following the first time, and logic means (COMP, FF) for incrementing or decrementing the second predetermined time by an incremental time in response to a comparison of the environmental temperature reached in the building at the end of the sum of the first and second real times with a setpoint temperature (SP) representative of the desired building temperature.</p> |
