First Claim
Patent Images
1. A water-control device comprising:
- an electrically controllable valve for dispensing water in a sanitary fixture;
a control circuit operatively connected to said valve and provided with a proximity detector for operating said valve in response to proximity of a user of said fixture and with system parameters and operating parameters including flow duration and operating range of said proximity detector;
a voltage source connected to said control circuit;
means in wireless communication with said control circuit for contactless setting of at least one of said system and operating parameters in said control circuit; and
at least one nonvolatile memory connected to said control circuit for storing said system and operating parameters independently of failure of said voltage source whereby operation of said control circuit with said system and operating parameters is automatically restored by said nonvolatile memory upon restoration of said voltage source to said control circuit.

Abstract
A fixture provided with proximity sensing for operation of the valve and contactless setting of the parameters of the control circuit for operating the valve of the fixture, can have a nonvolatile memory which is effective independently of the power supply for the control circuit so that the set parameters are maintained in the memory even on battery failure and are available to restore operation with the set parameters when power is restored.
