<p>A control system for a heating and/or cooling system (2) allows the temperature in a number of distinct spaces to be controlled to different values during different times of the day by providing a selector unit (16) in each of the spaces. The selector unit has a sliding contact potentiometer (20) for each of the sub-periods of the day so that the required temperature can be set. The selector units are connected to a common control unit (10) by a circuit (14) on which signals are transmitted in order to identify which of the preset temperatures is to be compared with the sensed temperature in order to control the source (4) of heating and/or cooling in the space.</p> |
