In other embodiments, a person skilled in the art may only use part of the steps of the control method of this embodiment, for example, the initial rotation speed V of the water pump may be calculated only based on the opening number X of the floor heating water valves, or the rotation speed V1 of the water pump may be calculated only based on the opening number X of the floor heating water valves. The control method of these variations should fall within the scope of the claims of this application.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
