<p>A high flow valve assembly and a low flow valve assembly are in parallel flow relation between an inlet and an outlet of a flush controller housing. The valve assemblies are opened by solenoid operated pilot valves under the control of a microprocessor based flush control system. A turbine directly measures flow through the low flow valve assembly and the control system computes flow through the high flow valve assembly to perform a flushing operation including an initial siphon trap flushing high flow porti on and a subsequent trap reseal low flow portion. A push button is pressed to o ne of two override positions either to provide a signal to the control system f or a normal flush operation or to open the high flow valve assembly independently of the control system for an emergency flush operation. A user detection system includes a pair of emitters and a pair of detectors defining an array of intersecting detection points in a skewed plane in which the control system can locate the position of a user. The controller can be configured for supplyin g flush water for either a toilet or a urinal, and for either right or left si de water supply entry.</p> |
