摘要： A setting unit acquires the temperature of an air-conditioned space, calculates the difference between the temperature of the air-conditioned space and a suction temperature as a correction amount ΔT, and transmits information of the correction amount ΔT to an air-conditioning apparatus. A controller of the air-conditioning apparatus controls the operation of the air-conditioning apparatus so that a control temperature obtained by adding the correction amount ΔT to the suction temperature becomes equal to a set temperature.
