ABSTRACT:
An energy-saving electronic thermostat operates by means of a single temperature probe. The rapid decrease in temperature of the probe when a window is opened causes the heating to be switched off or reduced by means of a comparator circuit combined with a network having a large time-constant. The device is employed in a fixed or mobile electric heating convector.
