Vitocal 350-G Pro

In cooling mode, the control unit decides whether the waste heat can be utilised for DHW heating and/or for charging the heating water buffer cylinder. If not, the waste heat is used to reheat the ground loop or is discharged to the outdoor air via a dry cooler.

The electrical equipment is already integrated inside the heat pump casing as standard. Factory-fitted contactors for fail-safe primary and secondary pumps, as well as protection for the compressor, guarantee straightforward installation and the safe and rapid integration of the large heat pump into the system.

The control philosophy was adopted from the Vitocal series for detached and two-family houses. Here too, the Refrigerant Cycle Diagnostic System (RCD) checks efficiency continuously and safeguards the efficient and reliable function at any operating point through the interaction between the electronic expansion valve (EEV) and the extensive sensor technology. 

With the optional addition of a Vitocom 300 communication module, a comprehensive range of settings and system optimisations can be undertaken from anywhere via internet or mobile phone.

As is the case for all heat pumps, the compressors emit noise in the 50 to 60 Hz range. Thanks to the high quality construction of the frame and anti-vibration casing components, it has been possible to keep this noise within the casing. Vibrations on the base support are barely perceptible as the 3-D antivibration construction is specifically designed to dissipate oscillations.
