From April 15, 1922

In 1885 another advance was made in that it was no longer necessary to have an attendant in the basement or at the source of the heat supply. This was the electro-pneumatic system. In 1890 the first thermostat was patented.

F.W. Powers, of the Powers Regulator Co, then took up the story, as he was indeed well qualified to do, since it was his father who patented the first thermostat in 1890. He spoke of the vapor disk type of thermostat, telling of the first instrument of this kind which was 18 inches in diameter and commonly called the “dishpan". He spoke principally on the application of the thermostat to individual room temperature control.
