The update separates outdoor units (ODUs) and indoor units (IDUs), making each outdoor unit compatible with all new indoor unit models. This allows installers to select an indoor unit that fits the specific needs of a building, whether for new construction or retrofits, independent of the outdoor unit’s output. The four new indoor units in the Vitocal 150


series are designed to reach flow temperatures up to 70°C, enabling the continued use of existing radiators without requiring underfloor heating.
