Sensor inputs ➜ Use
The following intended uses for the sensor input can be selected in the "Use" submenu:
If one of the following fan-speed control systems is selected in the "Type of control"
menu (see page 70), the use of the input for supply air or extract air must be deac-
tivated:
– Fan speed setting with control panel
– Temperature controlled
– Without supply-air fan/without extract-air fan
– Supply-air fan follows extract-air fan/extract-air fan follows supply-air fan
Sensor inputs ➜ Input type
If the following points are selected in the "Use" submenu:
– Measuring duct pressure
– Measuring volume flow
– Volume flow measurement with pressure sensor
the suitable voltage range for the used sensor can be selected in the submenu "input
type". Factory setting is 0-10V. The submenu "Input type" is not shown for the other
uses.
Sensor inputs ➜ Range start/range end
If a sensor input is activated in the "Use" submenu, a range start and a range end (e.g.
0-500 Pa or 30-100%) must be specified. In this case the external setting or the mea-
surable range of the sensor is displayed linearly on the selected input signal (e.g. 0-
10V).
Depending on the selected use, different physical variables can be entered, as the
following table demonstrates
