Can the motion sensor on the WS-301 be disabled, how? We occasionally need manual control only so the lights remain on until switched off.

Asked by: Larry
In the event of unit failure or if it is necessary to leave the load ON, remove the Service Jumper plug. This disables all automatic ON and OFF functions and the load can only be operated using the ON/OFF button. See the attached image to access the service jumper.
