ABSTRACT:
An improvement for a thermostatic control system of the type in which a heater having two electrical terminals is turned on when a conductive path is established between the two terminals and is turned off when the conductive path is opened, and in which first thermostat is used to open and close the conductive path. The improvement is a series combination of a remotely controlled electrical switch and a second thermostat, the series combination being connected to the heater terminals in parallel with the first thermostat. The second thermostat is normally set to a temperature greater than the temperature to which the first thermostat is set. The first thermostat controls the heater to standby temperature until a signal is applied to the remotely controlled electrical switch. Upon receipt of a predetermined signal, control is passed to the second thermostat which thereafter maintains a higher temperature. A second signal opens the switch, returning control to the first thermostat, and the temperature returns to the standby temperature.
