14. Humidity system
The humidity system is turned on with the humidity switch (4) located in the lateral control panel.
The MKF / MKFT alternating climate chamber is equipped with a capacitive humidity sensor. This results
in a regulatory accuracy of up to ± 2.5 % r.h. of the set point. The temperature-humidity diagrams (Figure
19) show the possible working range for humidity.

Range A: Control range of temperature and relative humidity.
Range B: Discontinuous range (no continuous operation, observe hints on defrosting, chap. 15)
Range C: Enlarged climatic range with optional compressed air dryer.
In climatic operation (with humidity) the preset temperature and humidity values must be situ-
ated within range A in order to achieve optimum regulation.
In the short-term set points in the discontinuous range (range B) can also be targeted.
On the edges of the control range (ranges A + B) the regulatory accuracies of ± 2.5 % r.H.
cannot be guaranteed.
With temperature and humidity set-points outside ranges A and B, humidification control is
automatically turned off. Humidity keeps being measured by the sensor and displayed, but
may deviate in case of condensation.
Entry of the humidity set-point 0 % r.h. in defined program sections permits completely turning
off humidity in Program Mode and thus attaining faster temperature changes.
