18.1 Making field settings
18.1.1 About making field settings
To configure the heat pump system, you must give input to the
outdoor unit's main PCB (A1P). This involves the following field
setting components:
▪ Push buttons to give input to the PCB
▪ A display to read feedback from the PCB
▪ DIP switches (only change the factory settings if you install a cool/
heat selector switch).

Mode 1 and 2
Mode Description
Mode 1
(monitoring
settings)
Mode 1 can be used to monitor the current
situation of the outdoor unit. Some field setting
contents can be monitored as well.
Mode Description
Mode 2
(field settings)
Mode 2 is used to change the field settings of
the system. Consulting the current field setting
value and changing the current field setting
value is possible.
In general, normal operation can be resumed
without special intervention after changing field
settings.
Some field settings are used for special
operation (e.g., one time operation, recovery/
vacuuming setting, manual adding refrigerant
setting, etc.). In such a case, it is required to
abort the special operation before normal
operation can restart. It will be indicated in
below explanations.

Push buttons
Use the push buttons to make the field settings. Operate the push
buttons with an insulated stick (such as a closed ball-point pen) to
avoid touching live parts.
