Hi @TrystanLea,
Have a bit of an edge case I noticed today whilst taking advantage of agile prices. On the Daikin with powerful mode for hot water, after the DHW hits 50+ and there is a call for heat the esbe valve closes, the compressor takes over the climate heating but the booster/immersion remains on to heat the water.
Currently I’m not reporting that as DHW on. Not sure if there is a decent way to handle it without splitting input feeds for DHW/climate.
P.s. if anyone wants to see how Agile plunge pricing can ruin your COP:
