1.1.3. Display (3)
The display (3) uses 7-segment numbers in full 3-digits. Additional signs include a small
circle, three square dots and two rectangular slashes.
The square dots are used with the externally printed text to visualize certain functions or
units. It is meant to denote the unit of the value shown in the display.
If the controller tries to match reference and actual flow this is shown as flashing dot of the
chosen unit.
If the actuator is turned on (power on) and the damper position feedback is activated the
display will show REF. The actuator travels from one end-stop to the other in order to learn
the maximum angle.
The Display shows a floating average of the actual flow from the latest 4s. The refresh rate
of this value is 1s.
