Fig. 6.15: Washing machine example
The washing machine will be switched on as soon as the system has produced 3.5
kW (Pon) for at least 15 minutes, and it will remain switched on until the system
power drops below 2 kW (Poff). In any case, the machine will remain switched on
for at least 120 minutes, so that the wash cycle can be completed. If “Pon” (3.5 kW)
could not be reached by 4 PM, the washing machine will anyway be switched on at
4 PM, then switched off at 6 PM.
