ABSTRACT:
A wireless remote control system has a hold-type wireless remote controller and a fixedly mounted main controller. When the wireless remote controller sets an operation time of a controlled object, it sends to the main controller a first code representative of a setting time corresponding to a difference between the operation time and a current time. Upon reception of the first code, the main controller sets the setting time at its timer. When a current time becomes the operation time, the wireless remote controller transmits a second code for operating the controlled object. If the main controller can receive the second code, the controlled object can be operated in response to the received second code. If on the other hand the main controller cannot receive the second code, the controlled object is operated by a time-up signal of the time in the main controller.
