Abstract
A temperature and pressure fluid control apparatus that may be nondestructively retrofitted to existing supply fixtures. The apparatus has a housing with at least one electromechanical valve actuator including a coupling that may be operatively connected to the valve stem of the supply fixture. The valve may then be driven with the actuator in accordance with the actual and the desired temperature and pressure. The housing and the coupling are spatially arranged so that the coupling will engage the existing supply valve when the housing is surface mounted on the wall or countertop so as to surround the supply valve.
