SETTING OF ALARM RESUME TIME

The alarm buzzer and remote alarm are silenced by pressing BUZZER key on the control panel during alarm condition. The buzzer and remote alarm will be activated again after certain suspension if the alarm condition is continued. The suspension time can be set by following the procedure shown in the Table 6 below.

The example in the table is based on the assumption that the desired duration is 20 minutes. Note: The duration is set in 30 minutes at the factory.

The settable alarm resume time are 10, 20, 30, 40, 50, or 60 minutes. The buzzer and remote alarm would not reset if the reset time is set in 000.

The setting of alarm reset time cannot be changed during the defrosting.

The buzzer and remote alarm during power failure or alarm testing cannot be silenced.

The set mode returns to the temperature display mode automatically when 90 seconds has passed without any key operation. In this case, any setting before pressing SET key is not memorized.
