<p>1. A fan-assisted radiator comprising in a casing (3) : an air inlet (5) and an air outlet (6) ; a motor and fan set (1, 2) producing an air flow through heating means (10, 10') which may or may not be energized according to the form of radiator operation ; means (16) for controlling the speed of the motor (1) ; and means (17, 18) for controlling the heating power of the heating means (10, 10'), characterised in that the heating means comprise a first heating element and a second heating element (10, 10'), the control means (17, 18) are adapted to control the heating power of the elements (10, 10') by a first form of control in which the first heating element (10) is energized continuously whereas the second heating element (10') is energized in a controlled proportional way by a control based on very short cycles and called "proportional", and by a second form of control in which the second heating element (10') is not energized, the first heating element (10) being controlled by a control based on longer cycles and called "on/off control", the first form of control being operative as a complement to the second form of control to produce fine control of the temperature of the room heated by the radiator.</p> |
