PURPOSE:To enable a simple composition of circuits to select the blow-off mode, and also enable a heater to start and shut down by allowing a interlock switch to be linked with temperature adjusting members so as to enable the switch to select a contact point which selects the stated air blow-off mode in relation to start-up and shut down of a cooler. CONSTITUTION:A rotary damper 3 which selects the air blow-off mode of an air conditioner, is rotated by a reversible DC motor 1, the rotational direction of which (1) is controlled by a switch-over switch 11. And a position detecting switch 20 is connected with the damper 3 enabling one out of numbers of blow- off modes to be selected where traveling contacts 21 and 22 are linked with the damper 3. In addition, an interlock switch 31 is provided including a traveling switch 32 which is linked with temperature adjust members such as an air mix damper 10 and the like. And both switches 20 and 31 are connected each other through a manual switch panel 14 which includes starting switches 15 through 18 that select the blow-off mode, automatic switches 19a and 19b, and switches 40a and 40b for a ON/OFF control of a compressor. |
