Fan output PWM (Pulse-width modulation) signal and triac output are already pre-addressed to specific terminals and
cannot be changed, all other outputs are free for configuration by commissioning. Outputs are free to be used for any
purpose.
Digital outputs are restricted by signal type and physical number of connections.
An output function is only allowed to be used once. Already used and configured terminal is greyed-out in the menu for
output type selection.
Analog and digital outputs have a selection for Auto/Manual modes and an adjustable value for Manual mode.
Manual mode selection overwrites all system related automatic functions. Analog output adjustable manual value
range is 0–10V and digital output values On/Off.
