PRO-D2i control unit

The Harvia PRO-D2i is a professional-grade control unit that takes sauna control to the next level. Its innovative 2-part design with patented technology supports up to 4 control panels, and the power unit can be installed either inside or outside the sauna — making it the perfect fit for any environment, from private homes to large commercial spas. With a maximum heating load of 10.5 kW, expandable with a power booster, the PRO-D2i is ready for even the most demanding setups. The additional output of up to 3.5 kW or 500 W dimmable opens up new possibilities — ideal for infrared heaters or infrared panels. Light and fan controls are fully switchable and dimmable up to 100 W, while adjustable heating time limits of 6, 12, 18, or 24 hours cater perfectly to commercial needs. Set your session with a minute-accurate digital timer, preset your temperature, or start remotely. Eco-mode, safety device connection, and a choice of single or dual sensor system ensure reliable and energy-efficient performance. Optional WiFi connectivity, an IP65-rated power unit, and house bus system integration make the PRO-D2i a future-ready solution for any sauna environment.
