Harvia PRO-LT3 Combi is a two-part control system designed to control an electric sauna heater with a maximum output of 10.8 kW together with a vaporizer. It supports both conventional sauna operation and Combi operation with a vaporizer.
The control unit allows temperature and operating time adjustment, preset start timing, ECO mode, lighting control and remote start. In Combi mode, the system controls both the sauna heater and vaporizer and supports humidity control according to the selected sensor configuration.
