Field settings
The 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.
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 under
. In this same 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
.
