<p>A controller is provided which includes a control unit for controlling the start of a climatization procedure in a building. The system includes a pulse generator which times the operations of the control unit and an equivalent electrical circuit which controls the operations of the control unit. The latter simulates thermal properties of the building during temperature conditioning operations, i.e., heating or cooling, and receives voltages representative of the inside and outside temperature of the building. The discharging, charging or equalization of voltages on condensors contained within the equivalent electrical circuit are used to determine the time for conditioning the temperature of the building after the conditioning system has been out of service for a given period of time and thus in calculation of the correct instant for starting the conditioning procedure by the control unit. A binary type frequency divider divides the output of the pulse generator to produce a pulse train of substantially lower frequency while a decadic counter converts the binary pulses into decadic pulses. The decadic counter produces pulses representative of different ending digits of the decadic numbers, e.g., 5, 7 and 9, and a plurality of different control means for controlling the start of the climatization procedure by the control unit are connected to individual outputs of the decadic counter. Thus, the sequence of operations of the control unit, under the control of the equivalent electrical circuit, takes place in an order determined by the end digits in question.</p> |
