Vitotrol 4+

Convenient and efficient operation of your heating system.
The Viessmann Vitotrol app allows you to operate Viessmann heating systems with Vitotronic control units. Operation of the app is simple, easy, and convenient from anywhere and at any time of the day. The Vitotrol app has a context-sensitive help function.

The Vitotrol app will provide access to the following functions of the Vitotronic heating circuit control unit:

• Easy setting of the heating program, set room temperature, domestic hot water temperature, holiday program and time program.

• Clear display of the operating parameters, including all relevant temperatures.

• Display of efficiency data, including solar yield and hours run.

To use all the functions of the Vitotrol app, the Viessmann Vitocom 100 type LAN1 communication device and a DSL router are required.

The Vitotrol app now contains the integrated Showcase functionality, which allows access to a simulated Viessmann heating system.
