HARVIA PRO-IP-D3I is an electric sauna heater control unit featuring an IP65-rated enclosure, designed for traditional and combined sauna heating systems. The unit supports electric sauna heaters with a power output of up to 10.5 kW, evaporators up to 3.5 kW and additional infrared radiators or heating panels.
An additional control output allows compatible infrared heating equipment with a total load of up to 3.5 kW to be switched on and off or the heating intensity of compatible infrared radiators with a power output of up to 500 W to be adjusted.
The control system allows users to adjust the sauna temperature from 30 to 110 °C, set the heater operating time and configure a preset start timer. With an optional humidity sensor, relative humidity can also be controlled. The system features an automatic post-drying programme, sauna lighting control and ventilation fan control.
The IP65-rated power unit enclosure provides protection against dust and water jets when correctly installed in accordance with the manufacturer's requirements. The power unit can be installed inside the sauna or in another suitable location, provided the specified environmental conditions are observed.
