Origin Only in defrost if DF01 = 1,3 (defrost en temperature/pressure or external
contact): when the defrost ends after the DF05 timeout.
Reset
 Stand - by or remote ON-OFF.
 Next defrost ends for temperature/pressure.
Restart
Automatic if next defrost ends for temperature/pressure, otherwise manual.

b1PH - b2PH: Pump Down stop alarm from pressure switch / Low pressure switch
Label on alarm

b1PH (Pump down stop alarm of the circuit 1)
b2PH (Pump down stop alarm of the circuit 2)
Origin Pressure switch: if CO36 = 1,2,3,4 and ID not active, the pump down stops
because of the timeout CO39.
Transducer: if CO36 = 1,2,3,4 and the set CO37 is not reached: the pump
stops because of the timeout CO39.
