Overview o the emergency programs
In case of an error the electronic switches in a emergency mode automatically This function enabled
restricted operating with the HansDampf.
„Emergency program“ is shown on display permanently.
Every program arises from a previous temperature sensor error message.
The message "emergency program" can be deleted by reset of electronic only.

The core temperature probe function is not available.
Temp. probe chamber 1 defect
Temp. probe chamber 1 defect (only

The core temp. probe is used as a chamber probe now. The
core temperature probe function is not available. Due the
position of the core temp. probe easy temperature
differences of the chamber temperature measurement are
possible.
