Field settings

The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user demand. Thereto, a number of so called field settings are
available. These field settings are accessible and programmable
through the user interface on the indoor unit.

Each field setting is assigned a 3-digit number or code, for example
[5-03], which is indicated on the user interface display. The first digit
[5] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.

A list of all field settings and default values is given in the 

"Field

settings table" on page 30

.  In this list we provided for 2 columns to

register the date and value of altered field settings at variance with
the default value.

A detailed description of each field setting is given under 

"Detailed
