<p>The control system comprises a microprocessor control unit (32), a control keyboard (29), means (34, 35) for taking readings of environmental data, means (42) for driving the organs for the execution of variations of the environmental data and display means (38, 40, 41). A programme storage unit (28) is associated with the control unit (32) in a position to contain several preset programmes which may be selected and modified by means of the control keyboard. At least one of the stored programmes determines and operating cycle which includes at least one phase in which leavening is stopped and two subsequent leavening phases of different duration and with different values of the environmental data. The duration of the cycle may be extendable up to one week and more. In such cases an alphanumeric display unit displays the days of the week.</p> |
