3.5. Sensor operating modes
The sauna control unit operates with two sensors. A temperature sensor (bench
sensor, F2) or a humidity sensor (FTS2) can be used as the second sensor.
Mode with bench sensor (F2)
In two-sensor operation 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.
In two-sensor mode with bench sensor, the humidity is timed. Only the set
value for the humidity level (in % of relative humidity) is displayed by the sauna
control unit. The actual humidity level in the sauna room when humidity is timed
depends on the size of the room and the evaporator capacity, and may deviate
from the set value.
Mode with humidity temperature sensor (FTS2)
When a humidity temperature sensor is used in two-sensor mode, the sauna
control unit displays the temperature which is measured by the humidity tem-
perature sensor as the actual temperature.
In two-sensor mode with humidity temperature sensor, the evaporator is regulated
in accordance with the humidity level measured in the sauna room. The actual
value for the humidity level (in % of relative humidity) is displayed by the sauna
control unit.
