A method for controlling a terminal apparatus that includes a display and that is used for an appliance control system for executing, from a car via a network, remote control on an air conditioner installed in a building, the terminal apparatus including a memory storing setting information specifying a plurality of air conditioners (AC1 - AC4) designated as targets of the remote control, the method comprising: causing (S2130, S2140) a computer of the terminal apparatus to judge, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using the setting information, whether or not there exists an air conditioner (AC1 - AC4) designated as a target of the remote control; and causing (S2331 - S2334) the computer to, in a case where there exist at least two or more air conditioners (AC1 - AC4) designated as targets of the remote control, obtain first position information indicating a current position of the car and second position information indicating a position of the building, and judge whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; the method characterized by further comprising causing the computer to, in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, present to a user, via the display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners (AC1 - AC4), the one common piece of display data including one common instruction portion for starting the certain remote operation; and causing the computer to, in a case where selection of the one common instruction portion by the user is detected, output control data for executing the certain remote operation on the at least two or more air conditioners (AC1 - AC4) to the network, and individually output, via the display of the terminal apparatus, for the at least two or more air conditioners (AC1 - AC4), pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners (AC1 - AC4). causing (S2130, S2140) a computer of the terminal apparatus to judge, in response to input of status information indicating that a certain period has not elapsed since power-on of the car, by using the setting information, whether or not there exists an air conditioner (AC1 - AC4) designated as a target of the remote control; and causing (S2331 - S2334) the computer to, in a case where there exist at least two or more air conditioners (AC1 - AC4) designated as targets of the remote control, obtain first position information indicating a current position of the car and second position information indicating a position of the building, and judge whether or not the position indicated by the first position information is within a certain region relative to the position indicated by the second position information; the method characterized by further comprising causing the computer to, in a case where the position indicated by the first position information is within the certain region relative to the position indicated by the second position information, present to a user, via the display of the terminal apparatus, one common piece of display data prompting a certain remote operation for the at least two or more air conditioners (AC1 - AC4), the one common piece of display data including one common instruction portion for starting the certain remote operation; and causing the computer to, in a case where selection of the one common instruction portion by the user is detected, output control data for executing the certain remote operation on the at least two or more air conditioners (AC1 - AC4) to the network, and individually output, via the display of the terminal apparatus, for the at least two or more air conditioners (AC1 - AC4), pieces of notification data indicating that the control data has been output for each of the at least two or more air conditioners (AC1 - AC4).
