1.5.4 Ventilator Volume Detection
(FA Sensor) (Option)
Sometimes FA (Fresh Air) is taken in with the
ventilator opened in the chilled mode. The FA volume
can be displayed on the LCD screen or recorded as
log with the FA sensor. When the ventilator is opened
in the frozen mode, the alarm E807 is displayed.
The wire reel mechanism and position meter
are installed inside of the FA sensor. The wire is
connected to the ventilator outlet cover so that
the movement of the cover opening and closing is
converted into the variation of voltage to send to
the controller.

Either "Ventilator with insect screen" or "Ventilator without
insect screen" is set for the unit installed with FA sensor
at factory referring to ※12 configuration set in paragraph
2.3.
●Setting of ventilation volume (FA volume)
Conduct the setting of ventilation volume after the
completion of the FA sensor calibration. FA sensor
characteristic differs between the ventilator opening
and closing. To display accurate FA volume, make
sure to follow the procedure of manual. Refer to ※
18 FA sensor calibration in paragraph 4.1.
●Event log recording
FA volume (m3/h) is recorded as event log at the
following timings.
1. At FA setting, at FA change
2. 0:00 am (Once a day)
