Control Series
Vitotronic 200 WO1C
With five output sizes, the Vitocal 300-G Pro large ground source heat pump reliably meets most requirements in residential and commercial properties.
Vitocal 300-G Pro – ground source heat pumps for large residential and commercial buildings
The Vitocal 300-G Pro heat pumps with up to 222.2 kilowatts are manufactured in series. The Pro series features all the characteristics of the highly efficient Vitocal 300‑G series. With five output sizes, most requirements from residential and commercial buildings can be reliably met. These appliances are standardised, enabling quick and comprehensive system design, as well as transparent cost calculation parameters. Higher output levels can be achieved by linking up to five Vitocal 300-G Pro in a cascade.
The water/water application with an intermediate brine circuit provides a reliable solution for the direct use of groundwater. An intermediate exchanger protects the standard unit against contamination and reduces the maintenance work for the heat pump.
The electrical equipment is already integrated inside the heat pump casing. Factory-fitted contactors for fail-safe primary and secondary pumps, as well as protection for the compressors, reduce installation effort and ensure rapid heat pump installation.
The control philosophy has been adopted from the Vitocal series for detached and two-family houses. Here too, the refrigerant cycle diagnostic (RCD) system checks efficiency continuously and ensures reliable function at every operating point through interaction with the electronic expansion valve (EEV) and the extensive sensor technology.
Easy to operate Vitotronic control unit with plain text and graphic display
The Vitotronic 200 regulates up to three heating circuits and, thanks to its natural cooling function, ensures a pleasant indoor environment on hot summer days. An extensive range of monitoring and system optimisation settings can be adjusted from anywhere, via the internet or a smartphone, utilising the Vitocom 300 communication module that is available as an option.

Combination with air/brine heat exchanger
In conjunction with an air/brine heat exchanger, the Vitocal 300-G Pro offers both cooling operation and the use of air as a heat source. The air/brine heat exchanger is connected to the heat pump via a brine circuit and enables heat recovery at an air temperature of down to -5 °C. Below -5 °C, a second heat generator takes over the heat supply in dual alternative mode. This allows for flexible system design and the formation of a robust system together with a second heat generator.
For such air/water applications, both the Vitocal 300-G Pro and the air/brine heat exchanger designed for this purpose are available. An attractive solution from a single source.
