20.2 Making field settings
20.2.1 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).
Field settings are defined by their mode, setting and value. Example: [2‑8]=4.
