Linking the Heat Pump to the Building Automation

 21 June 2024

The WAGO Automation Gateway makes it possible to intelligently retrofit heat generators from Viessmann

Efficiency is of primary importance in the building automation world. Seamless integration of different systems allows building operators to optimize resources and maximize user comfort. This also includes linking the heating technology to the management and control device.

Viessmann, one of the world’s leading manufacturers of heating and air-conditioning solutions, would also like to offer this possibility to its customers. This requires a straightforward and retrofittable solution, which enables communication between the devices and the management level in building automation systems. In search of a reliable partner for this project, Viessmann found WAGO, whose diversity and open communication systems impressed the HVAC specialists. A WAGO PFC200 was used as a gateway during this cooperation.

WAGO Automation Gateway

  • The WAGO Automation Gateway enables Viessmann devices to be connected to and intelligently networked with a building control system.

  • The Gateway functions as an interface between the device-specific CANopen® system bus and the classic building automation communication protocols.

  • The connection allows users to exploit integrated building automation systems, as well as remote monitoring, remote maintenance and external control of the Viessmann heat pumps.

The project required an interface between the heat pump and the management and control device

The idea for the solution arose in 2018/19, in connection with the introduction of the new “One Base” electronic platform at Viessmann. While developing this new control platform, Viessmann sought a solution for enumerating energy meters; they found an answer, including an M-Bus application, at WAGO. The next step was to connect the devices to the management and control unit. Due to successful cooperative ventures in the past and WAGO’s ability to develop tailored solutions in a modular design, Viessmann selected WAGO as their preferred partner.
