The "number of outputs controlled" parameter is fixed at 4.
On initialization, PILOT OUTPUT NUMBER has the value 1. On initialization, if the tank is in the state indicated
and if a sensor above the water is in the ON state, when the user program is executed, the INPUT 1 and INPUT
2 inputs are ON, INPUT 3 and INPUT 4 are OFF and OUTPUT 1 and OUTPUT 2 are ON.
Assuming that the tank is full, INPUT 2 changes to OFF and OUTPUT 1 changes to OFF. PILOT OUTPUT
NUMBER indicates the value 2.
Assuming that the tank is empty, INPUT 2 changes back to ON, OUTPUT 3 changes to ON and OUTPUT 2
remains ON.
Assuming that the tank refills, INPUT 2 changes back to OFF, OUTPUT 2 changes to OFF and PILOT OUTPUT
NUMBER indicates the value 3.
Assuming that the tank continues to refill, INPUT 1 changes to OFF, OUTPUT 3 changes to OFF and PILOT
OUTPUT NUMBER indicates the value 4.
6.5.51 Defrost
short Description
The defrost output changes to ON when the input temperature is less than the minimum temperature for a
time T (T being the cumulative duration of passages below the minimum temperature). If the temperature
