The sensor inputs for air handling units for continuously variable speed control of
the required fans are configured in the submenu "Sensor inputs". Sensor inputs
are used with external assignment of fan speed using a 0-10V signal, with fan
speed assignment via duct pressure control and volume flow control. The sub-
menus for setting sensor inputs are displayed for "Supply-air fan" and/or "Extract-
air fan".
Analogous to the "extract-air fan" submenu, the "supply-air fan" submenu has the
following submenus for setting sensor inputs:
– Usage
– Input type
– Range start
– Range end
– Filter constant
– K-factor
Depending on the selected purpose for the input, the submenus like "K-factor" are
hidden since the are not required (see sensor inputs Ü use ff from Page 77)
Sensor inputs ➜ Usage
The following intended uses for the sensor input can be selected in the "Use" sub-
menu:

Speed setpoint range 0-10V
Measuring duct pressure
Measuring volume flow
Volume flow measurement with pressure sensor
If one of the following fan-speed control systems is selected in the "Type of con-
trol" menu (see Page 71), the use of the input for supply air or extract air must be
deactivated:
– 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
