The operation of an object to be controlled, operation hour data, operation day-of-week data etc. are keyed in from a keyboard randomly and are displayed by a display unit, while at the same time these are stored in an input buffer. Upon depression of a transfer key, the correctness of the key-in items stored in the input buffer is checked by a microprocessor controlled by a program stored in a read only memory. When the item is incorrect, the display of the incorrect item is flashed in the display unit to request an operator to make a key-in again. When all the items are correctly keyed in, those are transferred to the memory portion to execute a given operation.
