PURPOSE:To make automatic load control by a body detecting portion compatible with manual load control by a manual operating portion by providing a control portion for controlling load conditions according to the output of the body detecting portion and that of the manual operating portion. CONSTITUTION:A body detecting portion 1 determines whether or not there is a body according to detection output transmitted from a body sensor 1A. A manual operating portion 2 includes a manual switch 2A which is manually turned on, and a manual switch 26 which is manually turned off, and the operating portion 1 inputs signals indicative of manual 'on' or 'off' operation. A control portion 3 controls load 4 according to the output of the body detecting portion 1 and that of the manual operating portion 2. The output of the body detecting portion 1 and that of the manual control portion 2 are input to the control portion 3 via a signal line 5, and control signals are supplied from the control portion 3 to the load 4 via a load control wire 6. Automatic control of the load 4 by the body detecting portion 1 can thus be compatible with manual control of the load 4 by the manual operating portion 2. |
