The Vitocal 300-A from Viessmann is an air source heat pump in the output range from 13.2 to 55.8 kW. An output of up to 279 kW is possible with a cascade of up to five Vitocal 300-A heat pumps.
The ViCare app provides intuitive heating control. Green for go – the user can see at a glance in the app whether their heating system is working as it should.
ViGuide is an app for trade partners. It has numerous functions for monitoring and controlling systems in both detached houses and apartment buildings and provides rapid access to Technical Service.
The Vitoconnect is the interface between boiler and app – the prerequisite for heating system operation via smartphone and tablet. It also provides remote system maintenance capability for contractors using the Vitoguide app.
The Vitotronic 200 (WO1C) is wall mounted inside the building for easy access, which facilitates straightforward commissioning and control of the heat pump. In a dual mode system, say in combination with a gas or oil boiler, the heat pump control unit can automatically start the second heat generator.
Furthermore, the Vitotronic 200 heat pump control unit is capable of communicating and, via the Vitocom 100 or Vitocom 300 communication module, allows the heat pump system to be set up, monitored and optimised over the internet with the Vitotrol app on a smartphone or tablet.
Where the Vitocal 300‑A is used in commercial applications, it can also be linked to a building management system using Vitogate 200 KNX.
