Heat pump
Under the control behaviour heat pump, the relay is activated as soon as the set
power P for the selected switch-on delay TD was surplus. If there is still enough
surplus after the hold time TH has elapsed, the system does not switch off but starts
the next cycle.

Load shedding
Under the control behaviour load shedding, the relay is activated as soon as the
set power P for the selected switch-on delay TD has been drawn from the mains. If
more energy than the set threshold value is still drawn after the holding time TH has
expired, the relay remains active. Only when the mains draw is below the set
threshold is the relay switched off after the switch-off delay has expired.
