Instructions for installation and use p. 11/38
In single-sensor mode, the sauna control unit only displays the set temperature
as standard. The actual temperature is not displayed. 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
8.5. Displaying the heater temperature in single-sensor mode on page 26)
The maximum humidity level which can be set is based on the temperature above
the heater, and 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.
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.
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
EN
from the set value.
Two-sensor 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.
