pump set has been correctly connected to the controller.
The pump set must be prepared for start-up according to the
installation and operating instructions for the pump and electric
motor. Set the pressure switches to the pressure values required.
See the installation and operating instructions for the pressure
switches.
The pump set is now operational and in automatic mode.
