An overheat detection system comprising: a controller configured to declare the overheat, and two wiring connections running the same path along a monitored system , each wiring connection connected in an independent loop with the controller , wherein each wiring connection is configured to react upon overheat on the monitored system , and the controller is configured to: - determine an electrical status of each wiring connection , at least among operative and inoperative, the inoperative status corresponding to an electrical anomaly thereof, - electrically connect or disconnect the wiring connections depending on the electrical status thereof, so that: • in case the controller determines that both wiring connections are in operative status, both wiring connections are maintained connected, • in case the controller determines that only one wiring connection is in inoperative status, the inoperative status wiring connection is disconnected, • in case the controller determines that both wiring connections are in inoperative status, both wiring connections are maintained connected, - declare an overheat in one of the following cases: • when the controller detects that both wiring connections are in operative status and both wiring connections react upon such overheat, • when the controller detects that only one wiring connection is in inoperative status and the only one operative wiring connection reacts upon such overheat, • when the controller detects that both wiring connections are in inoperative status, and at least one of such inoperative wiring connections reacts upon such overheat. a controller configured to declare the overheat, and two wiring connections running the same path along a monitored system , each wiring connection connected in an independent loop with the controller , - determine an electrical status of each wiring connection , at least among operative and inoperative, the inoperative status corresponding to an electrical anomaly thereof, - electrically connect or disconnect the wiring connections depending on the electrical status thereof, so that: • in case the controller determines that both wiring connections are in operative status, both wiring connections are maintained connected, • in case the controller determines that only one wiring connection is in inoperative status, the inoperative status wiring connection is disconnected, • in case the controller determines that both wiring connections are in inoperative status, both wiring connections are maintained connected, • in case the controller determines that both wiring connections are in operative status, both wiring connections are maintained connected, • in case the controller determines that only one wiring connection is in inoperative status, the inoperative status wiring connection is disconnected, • in case the controller determines that both wiring connections are in inoperative status, both wiring connections are maintained connected, - declare an overheat in one of the following cases: • when the controller detects that both wiring connections are in operative status and both wiring connections react upon such overheat, • when the controller detects that only one wiring connection is in inoperative status and the only one operative wiring connection reacts upon such overheat, • when the controller detects that both wiring connections are in inoperative status, and at least one of such inoperative wiring connections reacts upon such overheat. • when the controller detects that both wiring connections are in operative status and both wiring connections react upon such overheat, • when the controller detects that only one wiring connection is in inoperative status and the only one operative wiring connection reacts upon such overheat, • when the controller detects that both wiring connections are in inoperative status, and at least one of such inoperative wiring connections reacts upon such overheat. <EOS>
