Including a data acquisition unit () that periodically acquires various measured temperatures of a liquid pipe (), a gas pipe (), and an intake port from an air conditioner controller (), an operating state determination unit () that determines an operating state of an indoor unit () on the basis of the acquired various measured temperatures, a blowing temperature estimation unit () that estimates a blowing temperature from the indoor unit on the basis of the acquired various measured temperatures and an estimation model set in accordance with the determined operating state, and a blowing temperature display unit () that displays an estimated value of the blowing temperature.

There is provided air-conditioning control in a low power operation so as not to exceed a target demand power amount in a predetermined measurement period while preventing deterioration of comfortableness of a living space. There include a reducible-power-amount estimation unit configured to calculate, for each group, a reducible power amount by making indoor units perform, for each group, a shut-off operation for a minimum shut-off time in the first half of a demand time limit, and a reduced-power-amount determination unit configured to distribute, when a power consumption amount predicted by a power consumption amount prediction unit exceeds a target demand power amount after the first half of the demand time limit passes, the exceeding power amount to each zone, evenly distribute, in each zone, the distributed power amount to each group, and calculate, based on the reducible power amount of each group, a shut-off time of each group when each group performs the shut-off operation to reduce the distributed power amount.
