Making field settings
6.1.1
About making field settings
To configure the heat pump system, you must give input to the
compressor 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.
PC configurator
You can also make field settings through a personal computer
interface (for this, option EKPCCAB is required). The installer can
prepare the configuration (off-site) on PC and afterwards upload the
configuration to the system.
