Abstract
An apparatus for controlling flushing of a toilet device detects use of the toilet device and compares the actual number of uses against a preset number of uses which are permitted before flushing of the toilet device. When the actual number of uses equals the predetermined number of uses, the toilet device is flushed. At the first use of the toilet device after flushing, a timing cycle is initiated and the timing cycle will cause flushing of the toilet device unless there is the predetermined number of uses of the device within the period of the timing cycle.
