1.At the beginning of the start of the equipment, the nearest return circuit tends to have excessive flow and damage the flow of the most disadvantageous return circuit.
2.Practical measuring result indicates that (in accordance with the right picture), the excessive flow will not proportionally increase the energy-output of the hot exchange.
3.Excessive flow will bring about relatively long starting time of the most disadvantageous return circuit, and it will raise the energy-consuming obviously.
4.Each user adjusts the temperature setting of the temperature-controller according to one's own comfortability, and the switch-control of the electric valve can destroy the static balance of the pipe-net at any time.
5.Too high or too low temperature setting will also destroy the static balance of the original hydraulic system and waste energy.
