It is advised to configure the parameters in peak mode and solar mode as follows:
Solar mode
Level of excess solar energy that activates the device: 50 % of the heat pump compressor power
Minimum activation duration: 1 hour
Optionally: define the latest start time and duration to ensure that the device is activated before the peak hours
Peak mode
Maximum power consumption: 100 % of the heat pump compressor power
Peak target value: the max. power level that should trigger the devices to turn off
Peak mode type:
Predictive (capacity tariff in Flanders)
Direct
