Once the fault is remedied, the alarm cancels automatically.
- In the case of a faulty cabinet probe, it is nevertheless possible to start or continue a blast chill pro-
gramme with timer.
- A set temperature blast chill programme not yet started, will convert the setting to time.
- If the food probe is not inserted, a set temperature blast chill programme in progress will convert
the setting to time and the compressor check will be performed on the food probe instead of the
cabinet probe.
- A set temperature blast chill programme in progress with food probe inserted, turns the compressor
on and off on the basis of times memorised previously in blast chill or conversation phases.
