Abstract

A variable speed pumping system including a variable speed pump, a remote user device, and an auxiliary device is provided. The variable speed pump includes a motor, a drive, a housing including a drive cover, and an onboard controller. The onboard controller includes a plurality of buttons formed in the drive cover, a touchscreen interface positioned on the drive cover, a main circuit board including a non-transitory computer readable medium, the main circuit board being electrically coupled to the touchscreen interface, the motor, and the drive, a wireless communication unit electrically coupled to the main circuit board, and a selectively removable IO expansion module. The onboard controller is configured to control one of a flow rate of the pump or a speed of the motor for a period time and actuate the auxiliary device based on input received on one of the onboard controller or the remote user device.
