3. Main operation interface
Press RESET key or countdown, the system will enter to the main operation interface:

The preheating operation will be started after electrifying as if the preheating time is not zero.
During preheating operation, the unit can not be started until the operation is over.

If flashes, it means preheating operation andthe operation can be cancelled by pressing

down at the same time;
If turns on, it means that the auxiliary electric heating is effective and can be started.

means all buttons on the panel are locked;

means the button is invalid.
