You can use the default parameter setting with the P499RxP-107C transducer and R410a refrigerant within a range of operation that depends on the specific model of P499 transducer selected. All other applications require some parameter changes and may require different transducers.

The parameters shown highlighted in gray in Table 1 are the advanced parameters. To view and change these parameters, change P.160 from 9999 to 0.
