System for obtaining a uniform air temperature in a discrete space

A method of uniformly heating a discrete space using at least two electrically powered heaters comprising the steps of:

• affixing a master controller to one of said heaters;
• sensing the temperature of the ambient air immediately adjacent each of said heaters;
• transmitting a first control signal from the other of said heaters to said master controller indicative of the sensed ambient temperature immediately adjacent the other of said heaters;
• transmitting a second control signal from the one said heater to the master controller indicative of the sensed ambient temperature immediately adjacent the one heater;
• and
• transmitting a heater control signal from said master controller to said one and said other heaters to simultaneously vary the output of each heater in inverse proportion to the sensed ambient temperatures to substantially uniformly heat said discrete space.

A system for supplying conditioned air into a discrete space for obtaining a desired set point temperature within the space comprising:

• a plurality of units for providing conditioned air into said space, each of said units having an independent power supply cord for connection to a source of electrical power;
• one of said units including a master control and another of said units including a slave control, said master control including a temperature control for enabling a user to establish the desired set point temperature within the discrete space, each of the units including a thermostat for sensing the ambient temperature in the area of the discrete space immediately adjacent the respective unit;
• and
• communication devices associated with each of said units for enabling the master control on said one unit to simultaneously control the operation of each of said units, 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 units, said communication device transmitting a signal from said thermostat of said one unit to said master control indicative of the ambient temperature sensed by the thermostat on the said one unit, 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 unit and to the said another unit to simultaneously vary the operation of each of the units so that the temperature of the output air of each unit is in inverse proportion to the sensed ambient temperatures to substantially uniformly condition the temperature of the air in said discrete space to obtain said desired set point temperature.
