Programmable Logic Controller calculates the remaining heat of user automatically, and when user's heat surplus reaches the first data, Programmable Logic Controller adjustment control valve is to the first aperture lower than normal aperture; When the second data that user's heat surplus reaches lower than the first data, Programmable Logic Controller adjustment control valve is to the second aperture lower than the first aperture; When the 3rd data that user's heat surplus reaches lower than the second data, Programmable Logic Controller adjustment control valve is to the 3rd aperture lower than the second aperture; When the 4th data that user's heat surplus reaches lower than the 3rd data, Programmable Logic Controller adjustment control valve is to the 4th aperture lower than the 3rd aperture; When the 5th data that user's heat surplus reaches lower than the 4th data, Programmable Logic Controller adjustment control valve is to the 5th aperture lower than the 4th aperture; When the 6th data that user's heat surplus reaches lower than the 5th data, Programmable Logic Controller adjustment control valve is to the 6th aperture lower than the 5th aperture; Last when user's heat surplus reaches close to zero, Programmable Logic Controller adjustment control valve cuts out completely.
