Fan high static pressure setting.
If the static pressure of the outdoor unit fan increases, the airflow
decreases and the fan motor power input increases. The unit can
estimate the ESP via measurements.
Via this setting, the installer can set the ESP to a fixed level or
change the moment of ESP evaluation.
Note:
For an ESP level higher than 45 Pa, level 0 is kept for
reliability of the fan motor.

Commissioning
NOTICE
General
commissioning
checklist.
Next
to
the
commissioning instructions in this chapter, a general
commissioning checklist is also available on the Daikin
Business Portal (authentication required).
The general commissioning checklist is complementary to
the instructions in this chapter and can be used as a
guideline and reporting template during commissioning and
hand-over to the user.
NOTICE
ALWAYS operate the unit with thermistors and/or pressure
sensors/switches. If NOT, burning of the compressor might
be the result.
