Appendix I
In rare occasions, when nothing else will help, it is possible to reset the controller back to the default factory
settings. This can be done in two ways:
Use the function accessible through the menu Service – Test – Reset to defaults,
By setting dipswitch 4 of SW2 on the controller PCB to ON.
If for any reason it is not possible to use the software option to default the controller, it is possible to do it by setting
a dipswitch 4 of SW2 to the ON position and switch the controller on. Once the controller has booted, it will show a
warning that the system has been reset to the default factory settings. Once the system is running, do not forget to
switch the system off and slide dipswitch 4 back to the OFF position again!
