摘要

PROBLEM TO BE SOLVED: To suppress deterioration of user comfort while reducing a peak of power demand. ! SOLUTION: A control method of a heating system includes: an acquisition step of acquiring an output suppression instruction for showing an output suppression time zone; a defrosting condition determination step S803 for determining a first defrosting condition in a time zone other than an output suppression time zone, and a second defrosting condition in the output suppression time zone; and operation control steps S805, S807 for starting a defrosting mode when a defrosting start condition is satisfied, and for terminating the defrosting mode when a defrosting termination condition is satisfied. In the defrosting condition determination step S803, the defrosting starting condition or the defrosting terminating condition of the second defrosting condition is made to be different from that of the first defrosting condition so that the time in which an operation is performed continuously in the defrosting
