9.8 ECO Function
In order to limit the overlap of the switching on of the 3 zones, the ECO function has been introduced.
The ECO function delays the switching on of the second output compared to the first, and of the third output
compared to the second, but always remaining within the operating cycle time
In this way, if during the temperature control, the power of the 3 zones does not exceed 33% of use, when the
ECO function is activated, the shifting of the ignitions avoids the overlapping of the three ignitions, limiting the
current peaks.
If, on the other hand, the 33% threshold is exceeded, the power demand is added to the next zone, but in a
much less burdensome way.
By avoiding overlaps, consumption is optimized.

With ECO function
By activating the ECO function, the ignitions are distributed over the
available cycle time avoiding overlaps and therefore current peaks.
See parameter P53 on chapter 11 "Configuration parameter list"
Example of 3 zones in modulation at different control rates, you can see
that the signals add up.
