If you want the relay can stay at ON status until another dial in. then you can setup the GOT timer data to "999", then RTU5024 will work at the Switch Mode. Dial it to ON and dial it again will back to OFF. Then you can use the command: 1234GOT999# to set the device to switch mode. You can do according to the following picture:
