Abstract
An electronic temperature control method and apparatus unit for a mixing valve for plumbing fixtures. The loop gain in the control unit is at least approximately inversely proportional to the instantaneous slope of the characteristic curve of the mixing valve, and the slope of the characteristic curve is determined from the instantaneous conditions of valve opening, hot and cold supply temperatures and mix temperatures.
