Alarm can only be reset on this screen.



Press [▼] and [▲] keys down simultaneously..



The alarm is reset.

The [ALARM] lamp goes off.

The operation panel displays the circulating fluid temperature and the
circulating fluid set temperature.

The contact signal of the contact input/output communication stops.

(Refer to the Operation Manual for communication for details.)



[ ] lamp lights only when AL01 Low tank level is generated.
