Field Settings from Remote Controller
Field Settings and Test Operation
100
Airflow Adjustment (AUTO)
The volume of blow-off air is automatically adjusted to the rated quantity.
Make settings before performing the test operation of the outdoor unit.
Setting procedure
(1) Make sure that electric wiring and duct construction have been completed.
In particular, if the closing damper is installed on the way of the duct, make sure that it is open. In addition,
make sure that a field-supplied air filter is installed within the air passageway on the suction port side.
(2) If there are multiple blow-off and suction ports, adjust the throttle part so that the airflow volume ratio of each
suction/blow-off port conforms to the designed airflow volume ratio. In that case, operate the unit with the
operation mode "fan". When you want to change the airflow rate, adjust it by pressing the airflow rate control
button to select High, Middle or Low.
(3) Make settings to adjust the airflow rate automatically.
After setting the operation mode to "fan", enter the field setting mode while operation is stopped and then
select the Mode No. 11 (21), set the First Code No. to
7
and the Second Code No. to
03
.
(4) After setting, return to the basic screen (to the normal mode in the case of a wireless remote controller) and
press the ON/OFF button. Fan operation for automatic airflow adjustment will start with the operation lamp
turned ON. Do not adjust the throttle part of the suction and blow-off ports during automatic adjustment. After
operation for approximately one to fifteen minutes, airflow adjustment automatically stops with the operation
lamp turned OFF.
(5) After operation stopped, make sure that the Second Code No. is set to
02
as in the following table by indoor
unit with the Mode No. 11 (21). If operation does not stop automatically or the Second Code No. is not set to
02
, return to the step (3) above to make settings again.
Notes:
1. Make sure that the external static pressure is within the range of specifications before making settings. If it is
outside the range, automatic adjustment fails, which may cause an insufficient airflow volume or leakage of
water.
2. If the air passageway including duct or blow-off ports is changed after automatic adjustment, make sure to
perform automatic airflow adjustment again.
Compensating the Temperature around People
(For units with the infrared presence/floor sensor only)
Change the ratio between the suction air temperature and floor temperature used to calculate the temperature
around human.
The temperature around human 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 human can be changed with this setting.
• To reflect the effect of the temperature around the ceiling, select the "Priorities given on the suction air
temperature" (the Second code No.
02
).
• To reflect the effect of the temperature around the floor, select the "Priorities given on the floor temperature"
(the Second code No.
04
).
• The infrared presence/floor sensor can be disabled by selecting "Suction air temperature only" (the Second
code No.
01
).
