Installing humidity/temperature
sensor FTS II
Install the humidity/temperature sensor FTS II in the
sauna cabin about 15 cm below the ceiling and oppo-
site of the heating system.
Connect the humidity/temperature sensor FTS II only
with the supplied 150° C temperature-resistant con-
necting line or an equivalent temperature-resistant line.
On the outside of the sauna cabin, the temperature-
resistant connecting line can be extended with custo-
mary lines.
WARNING - Electric shock:
Run the power cables separate to other sen-
sor and control lines.
Protect single insulated lines with a pipe
(double insulation).
1. Run the line to the mounting location of the humi-
dity/temperature sensor FTS II 2 in the cabin wall
and fix in position with wiring clips.
2. Connect terminals of up to 150° C temperature-
resistant line to sensor terminals 3 according to
circuit diagram 7.
3. Conduct tests according to the chapter "Tests".
4. Fix humidity/temperature sensor FTS II 2 to the
cabin wall opposite of the heating system with two
wood screws 1 keeping a distance of 15 cm to
the ceiling.
