To make it possible to perform a variety of settings to individual equipment and to make it possible to simply execute a variety of settings from a remote place by irradiating a specific facility equipment with visible light and switching an operation mode of the facility equipment receiving this visible light to a normal operation mode or to an operation mode for setting a set value of the facility equipment.
A laser switch of setting equipment 9 is turned on, a visible laser beam emission part is made to emit a red laser beam, and a control part 7 of a facility equipment 6 to be desired to set is irradiated with the red laser beam. When the red laser beam has been received, the control part 7 switches its operation mode from a 'normal operation mode' to a 'setting mode' and receives setting data transmitted from the setting equipment 9. In order to execute a variety of settings in this 'setting mode', a set switch of the setting equipment 9 is operated and a set value for a variety of information is inputted. On the basis of these setting data, a setting of a variety of information is performed.
