| 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 | |

| 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 |
