Abstract
A control assembly in combination with a thermostatically responsive apparatus. In a preferred mode the principles of the present invention are applied to an infra-red heating system of the type including burner assemblies (12, 12') connected in series by a heating pipe (14), the assemblies being further connected by heating pipes (14) to a vacuum pump (40). The pump (40) is driven by a variable-speed electric motor (42) which is responsive to a thermostat (16) which may initiate, through control panel (15), operation of the burner assemblies. The burning rate of the burner assemblies is controlled by varying the speed of the electric motor and this is accomplished by the control assembly (44) which is responsive to indoor and outdoor temperature sensing devices (48, 50). The control assembly is initially programmed with climatic data which is correlated with operational speeds of the pump to give desired thermal operational characteristics of the burners at differing temperature ranges.
