PROBLEM TO BE SOLVED: To enable a set value becoming energy-saving to be changed over.SOLUTION: A first consumption energy calculation part 102 calculates a first consumption energy amount when a set value of heating temperature environment defined in advance in respect to a space to be air-conditioned is changed over to a higher temperature. A second consumption energy calculating part 103 calculates a second consumption energy amount when the set value of the heating temperature environment defined in advance in respect to the space to be air-conditioned is changed over to a lower temperature, and compares each of the calculated first consumption energy amount with each of the calculated second consumption energy amount. When the first consumption energy is lower, a changing-over to a higher temperature than the set value of the heating temperature environment is indicated and when the second consumption energy is lower, a changing-over to a lower temperature than the set value of the heating temperature environment is indicated.SELECTED DRAWING: Figure 1A |
