The 239 is more than enough to support the motor. We always use and accumulator with the 239. Not to increase flow but to save the pump motor. Without the accumulator the pump will cycle on and off every seccond. This will keep the pump from making a complete revolution. The accumulator will allow the pump to make several revolutions. The pump is a DC motor. It uses the most current on startup. If it is going of and on quickly it will overheat the motor.
The pressure sensor would be a good way to monitor the condtion.
The "e" might be here by juen but no firm date has been given. The "e" will be an add on to the 2d setup so installing after you have your system going will be just plug and play.
