The valve controller is selectively operative to control the position of the piston so as to enable liquid flow through a plurality of flow paths. A master controller wirelessly communicates with a plurality of slave controllers, including the valve controller. The master controller is operative to control conditions of the valve and an associated liquid treatment tank.
