All rooms within your home are safe with ViCare Smart Climate - even with some of them are not covered with radiator thermostat valves.
If some of the parts of your home are not connected to the installation, you can still assure that this given area is operating under the ViCare Smart Climate as well. It is called a “Home Zone” and can be activated at any time. For the Viessmann One Base heating device there are “Other Rooms”, referring to passive area at home, can be created via ViCare application during the commissioning process - each "Other Rooms" for each Heating Circuit.
The temperature in this area has to be set manually on radiator valves. It means that ViCare Smart Climate cannot measure the temperature there thus you cannot directly operate radiator thermostats. Yet, it is highly recommended to set Time Programs for “Home Zone” as well – either manually or with Time Assistant. It will allow ViCare Smart Climate to heat up this area according to your needs - and the only thing to do there will be increase or decrease the position of the valve every time you stop feeling comfortable.
