The C105S Logix is a control unit for a Combi heater, which can also be used to control Harvia’s separate Steamer and/or electric heater. The control unit controls the heat produced by the heater and the humidity produced by the steamer in the sauna room. There are separate sensors for both, which read the temperature and humidity rating. Running times and preset times for operation can be set accurately by adjusting the control unit regulator. The control unit also houses the sauna’s light and air-conditioning switches.
