Does this seem right for the parameters? I would have probe one in the keezer side and probe 2 in the refrigerator/fermenter side.
SP1 33,SP2 62
r1 4,r2 .1
a1 72, a3 32
c0 5,c2 inv
p5 2,SD 2
Assuming r0= ind
Freezer side turns ON at SP1+r1= 33+4= 37°F
OFF at SP1= 33°F
Fermenter side turns ON at SP2-r2=63-.1= 62.9°F
OFF at SP2= 62°F
Display will show fermenter side temp on the display( P4= SD2), pushing set
displays freezer temp.
a1 and a3 have no effect on the cooling or heating operation, only set point limit.
