10.4 Standard parameter settings
The standard parameter settings differ depending on the refrigerant. The tables below show the standard settings for refrigerant:
■
R134a
■
R134a and system with defrost
■
R404A
Making changes to these settings affects the functional safety of the system. Only make changes to the settings if you are familiar with
the outcome!
