Pressure Optimization	Pressure Stability	The pressure change curve is more stable, and the frequency change is smaller after stabilization
	Alternate Transition	Yes, the transition tends to be smooth and excessive (the transitional pump looks at the difference between the given pressure L and the feedback pressure P to adjust the frequency, and it will stop when L-P<0.2bar. If the water consumption suddenly increases at this time, the L-P>0.2 bar, alternating water pumps will speed up the frequency regulation pressure, when L-P=0.2bar, slowly adjust the frequency for a smooth transition)
Mode	Control Mode	Constant pressure, Constant differential pressur,Constant temperature, Constant differential temperature
	Linkage Mode	Synchronize, Master-slave, Big-small pump, One duty one standby, One VFD drive two pumps
	Manual/ auto Mode Switching	Can be switched by button or terminal. Button switch: press the   and  buttons at the same time for manual/auto switch (also switchable in case of failure) Terminal switching: S2-COM off: auto control  S2-COM on:manual control  In manual control, the manual frequency can be adjusted through the up and down buttons, and the influence of pressure is shielded, which is more comprehensive
