As a possible implementation manner, the control device can monitor the temperature difference between the supply water and the return water of the heating system; and determining the heat supply state of the heat supply system based on the temperature difference between the supplied water and the returned water of the heat supply system.
For example, if the temperature difference between the supplied water and the returned water is smaller than the first temperature difference, the heating system is determined to supply excessive heat.
For another example, if the temperature difference between the supplied water and the returned water is greater than the second temperature difference, it is determined that the heating system is insufficient in heating; wherein the first temperature difference is less than the second temperature difference.
For another example, if the temperature difference between the supply water and the return water is greater than or equal to the first temperature difference and less than or equal to the second temperature difference, it is determined that the heating system is heating normally.
It should be noted that the heat supply flow rate of the circulation pump and the working frequency of the circulation pump are positively correlated. The higher the working frequency of the circulating pump is, the larger the heat supply flow of the circulating pump is. The lower the working frequency of the circulating pump, the larger the heat supply flow of the circulating pump. Therefore, the embodiment of the invention can monitor and control the working frequency of the circulating pump so as to realize the control of the heat supply effect in the heat supply system.

For example, the first temperature difference may be a 10% decrease in the target temperature difference. The second temperature difference may be a temperature difference after the target temperature difference is increased by 10%.
As a possible implementation mode, when the temperature difference of the water supply and the water return is larger than the target temperature difference, the control device can increase the working frequency of the second circulating pump so as to improve the heat supply flow, reduce the temperature difference of the water supply and the water return and improve the heat supply effect.

As a possible implementation manner, when the heating system supplies excessive heat, the control device may adjust the first circulation pump or the second circulation pump based on steps S1031 to S1035 to improve the heating effect of the heating system.
And S1031, if the heat supply of the heat supply system is excessive, determining the circulating pump in the current heat supply operation.
S1032, if the heat supply of the heat supply system is excessive, the circulating pump in the current heat supply operation is the second circulating pump, and whether the working frequency of the second circulating pump reaches the minimum frequency or not is judged. If yes, step S1033 is performed. If yes, go to step S1035.
S1033, if the heat supply of the heat supply system is excessive, the circulating pump in the current heat supply operation is the second circulating pump, and the working frequency of the second circulating pump reaches the minimum frequency, timing is started, and the second duration is counted.

S301, if the heat supply of the heat supply system is excessive, the current heat supply running circulating pump is the first circulating pump, and the working frequency of the first circulating pump reaches the minimum frequency, and then the third preset time is determined based on the current water supply and return temperature difference.
In some embodiments, the control device may calculate a difference between the current supply and return water temperature difference and the target temperature difference, and determine the third preset time period based on the difference and the preset corresponding relationship.
The preset corresponding relation represents a corresponding relation between a difference value between the current supply and return water temperature difference and the target temperature difference and a third preset time length.
