This option wipes all configuration settings from memory then restarts the system. Default values will then
be loaded and the system will behave as if it were switched on for the first time. NOTE – Any options set
during commissioning will be lost and need to be re-entered.
Restart (Stop>Restart)
Restarts operation of the system. The BMS output will be de-activated and normal operation will resume.
