Field Setting from Remote Controller
(8) Setting the Rate of Human Detection
(For units with the infrared presence sensor only)
Set the sensitivity of the infrared presence sensor.
• The infrared presence sensor can be disabled by selecting the Second code No. 04.
(Note) When the infrared presence sensor is disabled, the remote controller menu does not display some
functions such as the automatic draft reduction, energy-saving operation in absence and halt in absence.
Mode No.

(9) Airflow Adjustment (AUTO)
External Static Pressure Settings
Make settings in either method (a) or method (b) as explained below.
(a) Use the airflow auto adjustment function to make settings.
Airflow auto adjustment: The volume of blow-off air is automatically adjusted to the rated quantity.
(b) Select External Static Pressure with Remote Controller Check that 01 (OFF) is set for the "SECOND CODE No."
in "MODE No. 21" for airflow adjustment on an indoor unit basis in Table 4. The "SECOND CODE No." is set to 01
(OFF) at factory setting. Change the "SECOND CODE No." as shown in table according to the external static
pressure of the duct to be connected.
Mode No.
11 (21)
(10) Compensating the Temperature around People
(When the unit is equipped with an infrared floor sensor)
Change the ratio between the suction air temperature and floor temperature used to calculate the temperature
around people.
The temperature around people is calculated using the values of the suction air thermistor and the infrared floor
sensor. The factory setting is Normal (the average value of the suction air temperature and the floor temperature
is applied). However, the rate at which the suction air thermistor and the infrared floor sensor affect the
temperature around people can be changed with this setting.
• To reflect the effect of the temperature around the ceiling, select the "Priority given on the suction air
temperature" (the Second code No. 02).
• To reflect the effect of the temperature around the floor, select the "Priority given on the floor temperature" (the
Second code No. 04).
• The infrared floor sensor can be disabled by selecting "Suction air temperature only" (the Second code No. 01).
Mode No.
