The external connector pos. 4 is used only to update the software but it has input to totally reset the equipment. This is
infact protected by external problems of such entity which could compromise its proper working.
Only in such situation the pump could go in protection (permanent block) but it is possible to reset its working by linking
for a while, connector Pins 3 and 4. Any damage can be stand by the microcontroller as it is protected by (over writing) acci-
dental caused by such problems.
