Static Pressure Setting Display.
A certified technician must set the external static pressure value(s). If the external static pressure is set incorrectly, the system will
malfunction.
Do not alter the external static pressure value that corresponds to each air flow level.
External static pressure value can vary depending on the indoor unit.
If by pressing the fan speed button during external static pressure setup, the fan speed is raised to the next level, the air flow value of
the previous fan speed will be maintained (external static pressure setting value is saved).
Assigning Air Flow
To assign an air flow for each fan speed, follow the steps below.
1. To access system installer setting mode, press and hold the temperature increase and mode selection
buttons simultaneously for approximately three (3) seconds. Choose setting code value “03” by press-
ing the mode selection button.
2. Use the fan speed button to select the desired fan speed. ( Lo→Med→Hi will display on the LED).
3. Use the temperature increase and decrease buttons to select the desired external static pressure set-
ting value (thereby assigning the respective airflow). External static pressure value range: 0~255; the
value will display near the lower right corner of the LED.
4. Press the on / off button to save the established settings.
5. To deactivate system installer setting mode after the settings have been established, press and hold
the temperature increase and mode selection check buttons simultaneously for approximately three
(3) seconds. If a button is not pressed for more than 25 seconds, the system installer setting mode
will automatically deactivate.
