SPECIFICATION OF ERROR
Outline Operation when error occurs Display in operation usually
When a basic performance and the function are ruined Displaying and heating stop EE0, EE1, EE2, EE3, EE8
When the dangers of the state of the high temperature and the ignition, etc. are
foreseen
Displaying and heating stop EE7
When you mistake the setting of the heating time Operation stop EE9
When neither the power supply nor the environmental condition are proper Operation stop EE4, EE6
When informing of the exchange time of parts Display Only CC1, CC2, CC3, CC4
