The counting unit is configured to count a thermal event such as an autoclave cleaning operation when the electrical device is not electrically powered. In one aspect, the counting unit includes a rotary member and an actuator, the actuator is configured to change shape from a first configuration to a second configuration when subjected to a predetermined temperature, wherein in the second configuration, the actuator engages the rotary member so as to rotate the rotary member. In another aspect, the counting unit includes a plunger, a drive and a heat resistant arm configured to release the plunger during a thermal event and retain the plunger when the electrical device is cooled down.
