point (range stop parameter p2) of a linear characteristic curve for the fan speed are parameterized
between 17 % and 100 %. Using the navigation buttons, the characteristic variables (red background of
the text) to be parameterised can be selected and the values can be set using the b / -.

Plausibility check for sensors with current output:
•
Concerns the analogue input on the master (terminal X2.7 / X2.8)
•
Error message if a value of 0-0.3 mA is applied at the input for more than 1s
•
Reset error if I > 3.5 mA for at least 1 s
2.3.2.5 Submenu Date/Time
In this menu, date and time are set.
Using the navigation buttons, the characteristic variables (red background of the text) to be parameterised
can be selected and the values can be set using the b /-.
2.3.2.6 Submenu Choose language
In this menu, the language for the TFT touch panel can be selected with the navigation buttons.
2.3.2.7 Submenu By-pass
In this menu, an existing by-pass is displayed. The function of the by-pass can be activated or
deactivated. The release of by-pass function is selected using the navigation buttons (red background of
the text) and by setting the checkmark, and is confirmed with Enter. Furthermore, the temperature
thresholds for opening and closing the by-pass flap can be selected using the navigation buttons (red
background of the text) and can be set using the b / -.
Abbreviation Designation Explanation / actions
x_ext_max Maximum
extract air
temperature
Setting range upper threshold: 20 °C…30 °C
The by-pass opens when the extract air temperature exceeds the
upper threshold value, and the intake air temperature is lower than
the extract air temperature.
x_ext_min Minimum
extract air
temperature
Setting range lower threshold: 13 °C…19.5 °C
The by-pass also opens when the extract air temperature falls
below the upper threshold value, and the intake air temperature is
higher than the extract air temperature.
