Control aux heater of heatpump Buderus WSW-196i

[janmisek]

I would like to utilize abundant power of my 10KW PV system during sunny days to accumulate energy into building. I am already able to raise compressor power of heatpump by setting hc1/manualtemp to higher value.

But during really sunny days I would like to force heatpump to use aux heater in parallel with the compressor to accumulate more energy into building.

I was able to run aux heater only using entity auxheateronly=on but I was not successful to run the aux heater in parallel with compressor:

Does anybody has knowledge how to force the heatpump to run aux heater in parallel with compressor?

Thanks in advance
