1. A home plumbing temperature control system for controlling water flow temperature, said plumbing system comprising(a) a biometric device for determining identification of a user;

  • (b) an electronic input control for setting a desired temperature range of water flowing out of plumbing system;

    (c) connection logic, said logic combining the biometric device input and electronic control input to pair users and temperature settings;

    (d) a thermal coupler for detecting said temperature of water coming into said plumbing system from an input supply;

    (e) an electronic output switch for activating an output display device to show indication of said desired temperature range;

    whereby said biometric device, input control, thermal coupler and output switch are combined together to provide a programmable temperature control system for output water based on user identification.
