Instructions for installation and use p. 12/60
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 controller 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 setpoint
for the humidity (in % relative humidity) is shown on the sauna controller display.
The actual humidity in the sauna cabin when the humidity is timed depends on
the size of the cabin and the evaporator output, and may differ from the setpoint.
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 sauna
controller displays the actual humidity (in % relative humidity) in the sauna cabin.
If a humidity/temperature sensor is connected, the “evaporator” menu item
cannot be hidden.
