PROBLEM TO BE SOLVED: To provide a terminal device capable of warning a user not to suddenly change a surrounding environmental temperature of an air conditioner.SOLUTION: A portable terminal 101, so as to operate an air conditioner in such a manner that a surrounding environmental temperature becomes a target temperature, displays a setting screen for receiving selection of one preset temperature from among a plurality of candidate temperatures in one time zone, and transmits the preset temperature selected by the user to the air conditioner as the target temperature. The portable terminal 101 includes: an acquisition unit 117a for acquiring an upper limit temperature and a lower limit temperature of the target temperature in the time zone; a calculation unit 117b for calculating a difference between the acquired upper limit temperature and the lower limit temperature; a determination unit 117c for determining whether or not the calculated difference is equal to or greater than a threshold value; and a display control unit 117d for, in the case where the difference is equal to or greater than the threshold value, displaying an item related to the upper limit temperature and the lower limit temperature in a form different from the case where the difference is below the threshold, on the setting screen.SELECTED DRAWING: Figure 2 |
