If the fault that started the timer is no longer detected for a period longer than the fault
release delay time t
fault, the timer will start from zero.
Faults which activate the fault timer are shown as SlowFault in
The fault timer uses the same pin (CPT) to set the time with an external capacitor C
as the preheat timer. The ratio between the preheat time-out time t
