ABSTRACT:
Apparatus for controlling a heat generating device having automatic adjustment of water temperature to heating requirements, and also for protecting such devices from being switched "on" and "off" too frequently, includes a control relay or a main relay having a "pause" imprint contact for switching "off" and an "on" contact, as well as a chronometric device for measuring how long the heat generating device is switched "on" and for setting an "off" pause imprint interval which is inversely variable according to the measured length of time the heat generating device is switched "on".
