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.
