A control system is disclosed which can be attached to equipment such as appliances or automobiles, or built in as a part thereof. The control system includes an enabling/disabling device such as a relay in a circuit in the equipment. A time setting device is used to program a microprocessor with the times when the relay will open and close-thereby disabling and enabling the equipment. The time setting device can only be used to set the times by a person having an authentic authorization device such as a card or a key. The card is read by a card reader and the information obtained is compared by the microprocessor with the authentic information. In the case where a key is the authorization device, it is used to close a circuit to the microprocessor. A liquid crystal display is provided to display time information, and a rechargeable battery is included to prevent changing the time by unplugging the equipment.
