Instructions for installation and use p. 9/30
3.4. Sensor operating modes
The sauna control unit can be operated with one or two temperature sensors.
Single-sensor mode (F1)
Single-sensor mode must be activated when starting up the sauna for the first
time (see 8.3. Activating/deactivating the single-sensor mode on page 22).
In single-sensor mode, the sauna control unit is operated with the heater sensor
with an excess temperature fuse (F1) only. In single-sensor mode, the sauna
control unit only displays the set temperature. The actual temperature is not dis-
played. Should the sauna control unit display the temperature above the heater
(F1) as an actual temperature in single-sensor mode, it must be activated when
starting up for the first time (see 8.4. Displaying the heater temperature in
single-sensor mode on page 22)
Two-sensor mode with bench sensor (F2)
In two-sensor mode with bench sensor, a second temperature sensor (bench
sensor) is installed above the rear sauna bench. The sauna control unit displays
the temperature measured by the bench sensor as the actual temperature.
