Abstract:
To provide a control unit capable of promptly starting a pump when a start condition of the pump is satisfied, and a pump device.SOLUTION: A control unit for a pump device is proposed which performs variable speed control on at least one motor-driven pump by at least one variable speed controller. The control unit controls the motor-driven pump by commanding a first signal for commanding operation/stop and a second signal for commanding an operational state to the variable speed controller. The control unit has a start condition for starting the pump while the pump is stopped, and a start standby condition predicting that the start condition is to be satisfied, and brings a pump where the start standby condition is satisfied, into a start standby state by commanding any one of the first signal for commanding the operation of the pump and a second signal for commanding start of the pump to the variable speed controller of the pump where the start standby condition is satisfied.SELECTED DRAWING: Figure 3
