Graph and table of Switching heaters on and off in the power mode 18 and 24kW

Note:

The heating group can consist of one heater, or 2, or 3 heaters, depending on the power of the boiler.

Also, the heating groups

do not always consist of the same heaters, but are formed from heaters which, at the time of switching on/off, selected by the
microcontroller based on the criteria for the minimum operating time of a particular heater, while respecting the symmetric load
according to phases.
