3.4. Sauna operating modes
The sauna control unit Pro D2/Pro D2i enables sauna mode operation. The sauna
control unit Pro D3/Pro D3i provides two operating modes, sauna mode and
combi mode.
Sauna operating mode
Dry heat is provided in sauna mode. The temperature in the room is high
(80 to 100 °C) The humidity level of maximum 10% is low.
Combi mode
The evaporator operates along with the sauna heater in combi mode.
The temperature in the sauna room is lower (approx. 40 to 65 °C) than in sauna
mode, with the relative humidity being considerably higher, spanning 35% to
approximately 70%. The maximum humidity level which can be set depends on
the temperature of the sauna. The higher the sauna temperature, the lower the
maximum humidity level which can be set.
3.5. Sensor operating modes
The sauna control units of the Pro D series can be operated with one or
EN
two sensors. A temperature sensor (bench sensor F2) or a humidity sensor
(FTS2, only Pro D3/Pro D3i) can be used as the second sensor.
