7. Set-point entry in “Fixed value” operating mode
In Fixed value operating mode you can enter a temperature set-point, a humidity set-point, the fan speed,
and the switching-state of up to 16 operation lines.
All settings made in Fixed value operating mode remain valid until the next manual change. They are
saved also when turning off the chamber or in case of toggling to Idle Mode or Program Mode.

see climatic diagrams, chap. 17.
Humidity
KMF
0 % r.h. up to 10 % r.h.
0 % r.h. to 98 % r.h.
see climatic diagrams, chap. 17.
Fan speed
40% up to 100 %
Reduce the fan speed only if required, because the spatial distribution of temperature and
humidity will also be reduced.
Technical data refers to 100% fan speed.
For the control range of temperature and relative humidity, see the temperature / humidity diagrams chap.
17).
With set-point type “Limit”, adapt the safety controller (chap. 12.2) or the temperature safety
device class 3.3 (option, chap.12.3) always when you changed the temperature set-point. Set
the safety controller set-point or the set-point of temperature safety device class 3.3 (option)
by approx. 2 °C to 5 °C above the controller temperature set-point.
Recommended setting: Set-point type “Offset” with safety controller set-point 2 °C.
When operating without humidity by setting “Control off” (chap. 6.3), the humidity tolerance
range function is automatically deactivated.
When operating without humidity by activated operation line “Humidity off” (chap. 7.3), set the
humidity tolerance range to “0” in order to avoid tolerance range alarms (chap. 11.4).
