The mechanism exhibits a temperature threshold (Tshd), for example an interruption threshold.

In this context, the generator temperature which is sensed by means of a temperature sensor is compared with a first temperature threshold value and a second temperature threshold value.

The power management circuit may compare the determined temperature to a temperature threshold.

The exhaust gas temperature threshold may be a hold-warm temperature and/or a regeneration temperature.

An over temperature alarming display apparatus.

The temperature is raised beyond a Vt shift temperature threshold for providing an on-state.

The temperature threshold value (29) is fixed, for example, at the freezing temperature point of the reagent (13).

Notification on exceeding a threshold temperature;

The thermoresponsive gel is controlled to be at a temperature below its threshold switching temperature.

The output signals of the temperature sensor that correspond to the actual temperature are compared in the generator regulator with a stored temperature threshold value.

In one embodiment, the processor reports a water leak when the water level reading exceeds a water threshold value and/or when the temperature reading exceeds a temperature threshold value.

At least one device (18) for temperature identification experiences an irreversible change of state when a threshold value for the temperature is exceeded.

If the sensed make-up air temperature is not above the temperature setpoint, decreasing the minimum make-up airflow.

The method comprises sensing a make-up temperature of the system and comparing the sensed make- up air temperature to a make-up air temperature setpoint.

After the temperature crosses the temperature threshold (810), the derate control current is derated at a designated rate (812).
