Cause Action
Dif ferent probes (P3,
P4, P5, P6, P7) have
the same configuration.
For example,
Correct the configuration
A13 = Ambient temp
(NTC 10 K),
A15 = Ambient temp
(NTC 10 K)
Dif ferent digital inputs
DI (DI1, DI2, DI3) have
the same configuration.
Correct the configuration
For example,
R04 = Door switch,
R07 = Door switch
Case 0: digital
compressor relay is
