Machine configuration
A Wizard (System builder menu) allows assisted configuration of the machine. The first choice
refers to the number of circuits (1, 2 or 3) by means of parameter PG01; in the case of dual and
triple circuit machines, the selection of the type of condensation, single or separate, (PG30) and the
presence, or otherwise, of an expansion unit (PG02) are also important. These 3 parameters define
the type of machine and the hardware supported, in accordance with the following table:

¹) If there is an expansion unit, the number of digital inputs and outputs increases, and it is
possible
to configure more hardware, depending on requirements.

²) In triple-circuit machines, inverter use is exclusively between compressors and fans.

³) The probes can also measure temperature by changing the relevant driver parameters: PH43,
PH44, PH45, PH47. Temperature is transformed into pressure by selecting the type of refrigerant
gas used (parameter PH31).
