 Commissioning mode: when powered on with pushbutton pushed, after several seconds the 
commissioning mode is activated with manual control over outputs and indication of inputs. After 10 
mins after last push or after reboot the controller goes to normal (control) mode. In the commissioning 
mode, all Modbus data are read-only.
