                    功能與原理：
                    
1.電信號啟動,向電磁鐵電DC24V杠桿掛鉤與棘輪脫離
                    
2.70°C（280°C）自動啟動，熔斷器動杠桿掛鉤與棘輪脫離
                    
3.手動啟動，手拉鋼索，杠桿掛鉤與棘輪脫離
                    
4.五擋風量調節，棘輪有五齒
                    
5.手動復位，用手柄轉動閥軸帶動棘輪，便棘輪與杠桿掛鉤嚙合
                    
6.輸出信號及聯鎖控制，控制器啟動凸輪壓下微動開關觸動頭，關態切換。微動開關數量2
