Abstract:
An electric heating system for a discrete space comprising:a plurality of electric heaters, each of said heaters having an independent electric power supply cord for connection to a source of electrical power; one of said heaters including a master control and another of said heaters including a slave control, said master control including a temperature control for enabling a user to establish a desired set point temperature within the discrete space, each of the heaters including a thermostat for sensing the ambient temperature in the area of the discrete space immediately adjacent the respective heater; and communication devices associated with each of said heaters for enabling the master control on said one heater to simultaneously control the heating operation of each of said heaters, said communication device transmitting a signal from said slave control to said master control, said signal being indicative of the ambient temperature sensed by the thermostat on the said another of said heaters, said communication device transmitting a signal from said thermostat of said one heater to said master control indicative of the ambient temperature sensed by the thermostat on the said one heater, said master control generating an output signal, said communication device receiving said output signal and transmitting second and third output signals to the said one heater and the said another heater to simultaneously vary the heat output of each heater in inverse proportion to the sensed ambient temperatures to substantially uniformly heat said discrete space.
