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 100Pa, 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.

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

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 6minutes to detect the room temperature by LL (Monitoring 1) or by L
(Monitoring 2).
