User experience, wherein control module 170 by Real-time Water buckling rate compared with default pressurized water buckling rate, it is real-time to judge
Whether hydraulic pressure data are more than default pressurized water buckling rate, default pressurized water buckling rate characterization central heater 100 with
The numerical value change range of Real-time Water buckling rate under aqueous mode, the range can be followed according to the actual of central hot-water system 10
Ring length of pipe is arranged with 600 quantity of water spot or water consumption, inventor it has been investigated that, the quantity used with water spot 600
When variation is by influencing the real-time hydraulic pressure data of water inlet 111, also, being reduced one by one with water spot 600, Real-time Water buckling rate will increase
Greatly, especially when transforming to Close All by use state with water spot 600, Real-time Water buckling rate is up to maximum, at this time
Real-time Water buckling rate will be above being reduced with water spot 600 and Real-time Water buckling rate when the case where non-Close All, preset
