English

• For setting and operation, refer to the “FIELD SETTING” in

the installation manual of the remote controller.

• Set the remote controller to the “FIELD SET MODE”. For

details, refer to the “HOW TO SET IN THE FIELD”, in the
remote controller manual.

• When in the “FIELD SET MODE”, select “MODE NO.

12” , then set the “FIRST CODE NO.” to “1”. Then set
“SECOND CODE NO.” to “01” for FORCED OFF and “02”
for ON/OFF OPERATION. (FORCED OFF at factory set)

With Wireless Remote Controller Used

Set the wireless remote controller address before using the
wireless remote controller.
For the setting method of the address, refer to the operation
manual provided with the wireless remote controller.

NOTE

• A “MODE NO.” is set on a group basis. To make a mode set-

ting on a room unit basis or check the setting made, however,
set the corresponding mode number in the parentheses.

1. Settings for Optional Accessories

• In the case of connecting optional accessories, refer to

the operation manuals provided with the optional acces-
sories and make necessary settings.

2. External Static Pressure Settings

Make settings in either method (a) or method (b) as
explained below. (FXMQ140PVE cannot be selected
method (a). Please select method (b).)
(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.
(1) Check that power supply wiring to the air conditioner

is completed along with duct installation. If a closing
damper is installed in the air-conditioning system,
make sure that the closing damper is opened. Fur-
thermore, check that the air filter as a field supply is
attached to the air passage on the suction side.

(2) If there are a number of air outlets and inlets, adjust the

throttles so that the airflow rate of each air outlet and
inlet will coincide with the designed airflow rate. At that
time, operate the air conditioner in “fan operation mode”.
To change the airflow rate, press and set the airflow
adjustment button of the remote controller to HH, H, or L.

(3) Make settings for airflow automatic adjustment. After

setting the air conditioner to “fan operation mode”,
stop the air conditioner, go to “FIELD SET MODE”,
select “MODE NO. 21” (11 in the case of group set-
tings), set the setting “FIRST CODE NO.” to 7, and set
the setting “SECOND CODE NO.” to 03.
Return to normal mode after these settings, and press
the ON/OFF OPERATION button. Then the operation
lamp will be lit and the air conditioner will go into fan
operation for airflow automatic adjustment. Do not
adjust the throttles of the air outlets or inlets during
automatic adjustment of the air conditioner. After the
air conditioner runs approximately one to eight min-
utes, the air conditioner will finish airflow adjustment
automatically, the operation lamp will be turned OFF,
and the air conditioner will come to a stop.

Table 4

(4) After the air conditioner stops operating, check with

“MODE NO. 21” on an indoor unit basis that 02 is set
for the “SECOND CODE NO.” in Table 4. If the air
conditioner does not stop operating automatically or
the “SECOND CODE NO.” is not 02, repeat steps
from (3). If the outdoor unit is not turned ON, U4 or
UH as explained in Table 8 will be displayed. This dis-
play is not problematic, because this function is set
for the indoor unit. Continue setting the function.
After setting this function, be sure to turn ON the out-
door unit before the test operation of the outdoor unit.
If any other error is displayed, refer to Table 8 and the
operation manual provided with the outdoor unit and
check the defective point.

CAUTION

• If there is any change after airflow adjustment in the ventila-

tion paths (e.g., the duct and air outlet), be sure to make air-
flow auto adjustment again.

• Consult your Daikin representative if there is any change in

the ventilation paths (e.g., the duct and air outlet) after the
test operation of the outdoor unit is finished or the air condi-
tioner is moved to another place.

(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 set. Change the “SECOND CODE
NO.” as shown in Table 5 according to the external static
pressure of the duct to be connected.
(1) The “SECOND CODE NO.” is set to 07 (an external

static pressure of 100 Pa) at factory set. (FXMQ40 ·
50 · 63 · 80 · 100 · 125 · 140PVE)
The “SECOND CODE NO.” is set to 02 (an external
static pressure of 50 Pa) at factory set. (FXMQ20 · 25
· 32PVE)
*1 The FXMQ50 · 63 · 80 · 100 · 125PVE cannot be

set to 30 Pa.

*2 The FXMQ40PVE cannot be set to 180 or 200 Pa.
*3 The FXMQ20 · 25 · 32PVE cannot be set to 110-

200 Pa.

*4 The FXMQ140PVE cannot be set to 30 Pa and

150-200 Pa.
