Yes, you can change the operating mode even when the ViCare single room control solution is enabled. You can find this possibility under Settings->System Settings->Heating circuit n.
For example, you can change from “Heating & DHW” to “DHW only”. Please note that the availability of specific program modes differs between boiler types.
Remark: Please note that the single room control solution will only work when the boiler is in “Heating & DHW” mode.
