After a single adjustment, the controller recalculates the actual values of the actual heating demand load and the pipeline transmission and distribution heat load and determines whether the actual heating demand load is equal to the pipeline transmission and distribution heat load. And if the actual heating demand load is equal to the pipeline transmission and distribution heat load, stopping adjusting the outlet water temperature of the boiler and the operating frequency of the water pump. And if the actual heating demand load is not equal to the pipeline heat transmission and distribution load, adjusting the outlet water temperature of the boiler and the operating frequency of the water pump again according to the adjusting logic. The controller continuously cycles the adjustment logic until the actual heating demand load is equal to the pipeline heat transmission and distribution load.

And then, a preset pressure threshold value is called, the return water pressure of the pipeline is compared with the pressure threshold value, and the size between the return water pressure and the pressure threshold value is judged. When the pipeline backwater pressure is smaller than the pressure threshold value, in order to avoid that the pressure in the pipeline is too low and the flowing of hot water in the pipeline is influenced, the controller forcibly increases the operating frequency of the water pump according to a third adjustment amount until the pipeline backwater pressure is not smaller than the pressure threshold value.
Further, the step of retrieving the reference operating condition parameter includes:
