A system and related method for touchless control of an aircraft lavatory water supply is disclosed. An aircraft lavatory touchless manifold includes dual solenoid powered water valves opening and closing to regulate water flow through each of a cold conduit and a hot conduit as commanded by user touchless input to a manifold microcontroller commanding the valves. An aircraft input commands a temperature range while a thermal sensor in a mixed water conduit provides output temperature feedback to the manifold microcontroller for positive control of the output temperature. The manifold microcontroller commands opening and closing of the dual solenoid powered valves to create a ratio of opening time between the valves. The solenoid powered valves provide a cost effective and reliable solution offering efficient linear valve operation and effective temperature and flow control.
