Setting: External static pressure
INFORMATION
▪ The fan speed of the indoor unit is preset to ensure the
standard external static pressure.
▪ To set a higher or lower external static pressure, reset
the initial setting with the user interface.
Settings for external static pressure can be achieved in 2 ways:
▪ Using the airflow automatic adjustment function
▪ Using the user interface
To set external static pressure by airflow automatic adjustment
function
NOTICE
▪ Do NOT adjust the dampers during the fan only
operation for airflow automatic adjustment.
▪ For the external static pressure higher than 100 Pa, do
NOT use airflow automatic adjustment function.
▪ If the ventilation paths have been changed, perform the
airflow automatic adjustment again.
▪ Test run MUST be done with a dry coil, run the unit for 2 hours
with fan only to dry the coil.
▪ Check if the power supply wiring, duct, air filter are properly
attached. If the closing damper is installed in the unit, make sure it
is open.
▪ If there is more than one air inlet and outlet, adjust the dampers so
that the airflow rate of each air inlet and outlet is conform with the
designed airflow rate.
1 Operate the unit in fan only mode prior to using the airflow
automatic adjustment function.
2 Stop the air conditioning unit.
3 Set the value number “—“ to 03 for M 11(21) and SW 7 and
continue according to the following table:
Setting content: Then

M SW —
Airflow adjustment is OFF 11(21) 7 01
Press ON/OFF to return to normal operating
mode.
Possible consequence: The operation lamp
will light up and the unit will start the fan
operation for airflow automatic adjustment.
03
Operation stops after 1 to 8 minutes.
Possible consequence: Setting is finished
and the operation lamp will be off.
02
4 After airflow automatic adjustment is finished check if the value
number “—“ is set to 02. If there is no change, perform the
setting again.
To set external static pressure by the user interface
Check the indoor unit setting: the value number “—“ must be set to
01 for
M 11(21) and SW 6.
1 Change the value number “—“ according to the external static
pressure of the duct to be connected as in table below.

Setting: Air volume when thermostat control is OFF
This setting must correspond with the needs of the user. It
determines the fan speed of the indoor unit during thermostat OFF
condition.

Setting: Time to clean air filter
This setting must correspond with the air contamination in the room.
It determines the interval at which
"Time to clean filter" notification
is displayed on the user interface.

Field settings are defined as follows:
•
M : Mode number – First number : for group of units – Number between brackets : for individual unit
• SW : Setting number
• —: Value number
•
: Default
(2)
Fan speed:
•
LL : Low fan speed (set during thermostat OFF)
• L : Low fan speed (set by the user interface)
• Setup volume : The fan speed corresponds to the speed the user has set (low, medium, high) using the fan speed button on the user
interface.
• Monitoring 1, 2 : The fan is OFF, but runs for a short time every 6 minutes to detect the room temperature by LL (Monitoring 1) or by L
(Monitoring 2).
