Circulating pump is shut down, then the power of the first outer net circulating pump is turned down one grade, and repeats second step and the 3rd step.
7. a kind of using method of transmission ＆ distribution flow balance controller as claimed in claim 3, it is characterised in that by following steps
Suddenly carry out：
The first step, start the first gas fired-boiler, the first boiler circulation pump, the second gas fired-boiler, the second boiler circulation pump, outside first
Net circulating pump；
Second step, after time interval t, by pressure transducer gather return main in pressure of return water P, and by collect return
Water pressure P is delivered to controller；
3rd step, by the pressure of return water P for collecting and return water temperature desired value P for setting0It is compared；
As P ＜ P0When, then the power of the first outer net circulating pump is heightened into one grade, and repeat second step and the 3rd step；If the first outer net
The power of circulating pump has been adjusted to highest gear, then start the second outer net circulating pump, and repeat second step and the 3rd step；If outside second
Net circulating pump has been turned on, then the gear of the second outer net circulating pump is heightened one grade, and repeats second step and the 3rd step；
Work as P=P0When, then repeatedly second step and the 3rd step；
As P ＞ P0When, then the power of the second outer net circulating pump is turned down into one grade, and repeat second step and the 3rd step；If the second outer net
Circulating pump is shut down, then the power of the first outer net circulating pump is turned down one grade, and repeats second step and the 3rd step.
