Instructions for installation and use
● Excess temperature fuse
The excess temperature fuse is installed in the housing for the heater sen-
sor. Should the sauna heater continue heating after reaching the preferred
temperature due to a defect, the excess temperature fuse switches the sauna
heater off at a temperature of approx. 139 °C.
3.4. Sauna operating modes
The sauna control unit Pro C3 provides two operating modes, sauna mode and
combi mode.
Sauna 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 unit can be operated with one or two sensors. A temperature
sensor (bench sensor, F2) or a humidity sensor (FTS2) can be used as the
second sensor.
Single-sensor mode (F1)
Single-sensor mode must be activated in the technician menu (see 8.2. Settings
in the technician menu on page 29).
In single-sensor mode, the sauna control unit is operated with the heater sensor
with excess temperature fuse (F1) only. This is included in the scope of delivery.
