In program mode, indicates current displayed function is smoke
related parameters.
ON
In executing smoke learning function.
Flashing
FLOW
In normal operation, indicates the reading on numerical display
is current airflow percentage.
ON
In program mode, indicates current displayed function is airflow
related parameters.
ON
In executing flow normalization.

The flashing indicators of smoke learning or air flow labeling will not go off due to switching the
numerical tube in display. example: In air flow labeling stage, the air flow indicator flashes, if
numerical tube switched to display smoke value at this time, the smoke indicator will become
normal ON with air flow indicator in flashing; switch to display the air flow value at this time, the air
flow indicator will flash; in switching to display temperature, the air flow indicator will flash, temp.
Indicator normal ON; the rest may be deduced by analogy, when airflow labeling ended, the air flow
indicator will stop flashing.

Beeper
There are the following beeper modes that the beep frequency is different when the device is in
alarm or fault status. Users can change the beeper mode according to their application.
