Abstract
An air-conditioning system has an air-conditioning unit and a controller which includes a timer setting unit for establishing data including at least one time zone in the time of one day and an operation status in the time zone for the air-conditioning unit. The controller also has a memory for storing the data established by the timer setting means, and operation control unit for controlling operation of the air-conditioning unit according to the data stored by the memory. The timer setting unit includes a first setting unit for establishing the data altogether for all days of the week, a second setting unit for establishing the data for a plurality of groups divided from the days of the week, and a third setting unit for establishing the data individually for the days of the week. The first, second, and third setting units are selected by the timer setting unit to establish the data. Each time new data is established by either one of the first, second, and third setting units. The timer setting unit corrects the data stored by the memory into the new data and stores the new data in the memory.
