r0 & r1 parameters setting value depends of the refrigerant choice “r3”.
r3 is set as default for R404A.
r3 Refrigerant
0 = no temperature conversion
1 = R22
2 = R134a (not possible for units including Copeland Digital Scroll compressors)
3 = R507
4 = R404A
5 = R407C (not possible for units including Copeland Digital Scroll compressors)
NOTE
: R134a cannot be used for Copeland EazyCool™ condensing units with two
