PURPOSE:To conserve energy and improve comfortableness and operability by providing a floor heating device and a fan heater and by detecting temperatures at the surface and at higher parts of a room over a floor thereby operating both heaters linked together. CONSTITUTION:A floor heater is controlled via a floor heater driving circuit 11 by inputting in a comparator 10 signals of a floor temperature detector circuit 8 and a setting device 9. Signals from a higher part temperature detector circuit 14 and a lower part temperature detector 18 compared in a comparator 19 controls a fan heater via AND gate 13 and a fan heater driving circuit 17. When a manual-auto switch 12 is turned to manual, signals from the lower part temperature detector circuit 14 and a room temperature setting device 15 are compared in a comparator 16 and a command signal is outputted to a fan heater driving circuit 17. The floor heating and fan heating are thus interlockingly controlled, conserving energy and improving comfortableness and operability. |
