| Multi-motor mode |
The inverter can control up to 4 motors simultaneously. 3 main motors can be set as inverter operation or commercial power operation, thus simplifying the constant-pressure water supply system. |
Timing motor-
alternation |
In a multi-motor system, the function of timing motor-alternation should be set in order that individual motors have the same operating time. When the continuous operating time of a motor reaches the set value and there is another motor in stop state, the inverter will automatically switch the operation between thees two motors(that is, the running motor stops, the other one starts) .
Motor-alternation time: 0 ¡« 1000 hours. |
| Sleep |
