<1> Only if there is a temperature sensor (p0601 = 2).
<2> Only if <1> are not met.
<3> If p0318 = 0 A, then p0305 will be used as reference current.
The lower p0611 and the lower the reference current of the thermal motor model 1 (I2t), the faster A07012 is reached.
<4> p0605 also defines the target temperature for p0034 = 100%. Therefore, p0605 has no influence on the time up to alarm A07012.
<5> If p0610 = 12.
