Abstract (en)

[origin: EP2851635A1] A method of controlling a heating system includes: obtaining an output modulation instruction indicating an output modulation period (S101); determining a first defrost condition for a period outside the output modulation period and a second defrost condition for the output modulation period (S102, S103); and causing a defrost mode to start (S112) when a defrost initiation condition is met (Yes in S111) and the defrost mode to stop (S114) when a defrost termination condition is met (Yes in S113). In the determining (S102, S103), a continuous operation time in the defrost mode under the second defrost condition is made to be shorter than under the first defrost condition by making the defrost initiation condition or the defrost termination condition in the second defrost condition different from that of the first defrost condition.
