It is adapted to be output to the circuits 4a and 4b.

Then, the control circuits 4a and 4b include the whole / foot step selection circuit 11,
It is connected to the output side of a CPU 14 which receives the outputs of the use time setting circuit 12 and the use pattern selection circuit 13 and performs storage / control. In this case, the use pattern selection circuit 13 has a third
As shown in FIGS. (A) to (C), there are three patterns of (A) heating only for initial preheating, (B) heating for a set time (h hours) including initial preheating, and (C) initial heating plus continuous heating. It is registered in advance as a usage pattern, and one of these three patterns is selected. In FIG. 3 (B), the heating power increases in the latter half of the use time in order to correct the decrease in room temperature. Further, the whole / foot step selection circuit 11 is a circuit for selecting the whole foot area, the foot area, and the chest area, and its output is also connected to the use time setting circuit 12 and the use pattern selection circuit 13. As a result, You can set and select different usage times and usage patterns with the lower part of the foot. Furthermore, the output selected or set in each circuit is output via the CPU 14 to the temperature setting display circuit 1
