Manual modes SCC_WE / Boiling point recognition
Steam mode in relation to boiling point recognition
During self test (after initial installation) the unit will determine the installation altitude by water boiling
point recognition.
As the boiling temperature declines with increasing altitude above sea level, the water boiling point
determines the installation altitude.
During self test the steam production will be active until the quenching sensor B2 reaches 70°C
(158°F). At this time the pcb will memorise the temperature measured by the interior cabinet sensor B1
as the boiling point temperature at the actual point of installation.
To run a manual cooking mode the following steps must be taken:
1. Cooking mode is selected.
2. Time or core temperature is selected.
3. Cabinet door is closed (door contact).
4. Fan motor is running (speed signal via bus).
5. In wet modes (Steam, Combination) the steam generator must be filled with water (level electrode)
6. In wet modes (Steam, Combination) the steam generator will be preheated
(thermocouple steam generator)
