Eventhough many functions are not accessible via integration once boiler configuration (parameter 228 in the menu) changed from 1 (boiler with water heater sensor) to 0 (default configuration without sensor), possibly due to packets corruption on the way or some specific bit sequence. It caused Genus One model not being able to handle DHW.
