OPERATING INSTRUCTIONS

Setting of alarm resume time

The alarm buzzer is silenced by pressing BUZZER key on the control panel during alarm condition (Initial setting 100: The remote alarm is not silenced).

The buzzer 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 3 below.

The example in the table is based on the assumption that the desired duration is 30 minutes. Note: The duration is set to 100 (no alarm resume time) at the factory.

The settable alarm resume time is between 10 and 60 minutes with 1 minute increment. (The setting is 010, 111, ------- 159, 160). The buzzer would not reset if the resume time is set in 000.

The buzzer is ON when the resume time is changed in F25 while the resume time is counted (the buzzer is silenced by BUZZER key). The count of resume time is stopped.

The setting cannot be changed during power failure.

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 ENT key is not memorized.

It is selectable whether the buzzer is in conjunction with the remote alarm or not when the buzzer is silenced by BUZZER key. (The remote alarm is not in conjunction with the buzzer by factory setting.)

The remote alarm is activated in conjunction with the buzzer if the third digit “1” is set to “0” in the step 5 above
