Relative humidity and rotation speed signals from fans are already pre-addressed to specific terminals and cannot be
changed, all other inputs are free for configuration by commissioning. Inputs are free to be used for any purpose.
Universal input (UI) configured as universal analog input (UAI) can be configured for several inputs because multiple
sensors of the same type can be used. Universal analog inputs (UAI) have only selections for RH Sensor (RH), CO₂
Sensor (CO₂), Supply Air Fan Control (SAFC) and Extract Air Fan Control (EAFC) wired configurations.
Analog input (AI) temperature sensors are not allowed to be configured more than once.
Same user modes can be configured on multiple digital inputs (for example multiple bathrooms can be connected to dif-
ferent digital inputs with Refresh mode configured for each.
Digital inputs can be configured to be normally open (Normally Open (NO)) or normally closed (Normally Closed
(NC)). Default setting is Normally Open (NO). Not available for wireless inputs.
A time delay for user modes activated via digital input can be switched off or enabled. Time delay indicates how long
the user mode remains active after its duration of operation has expired.
PDM (pulse density modulation) input for relative humidity (RH) sensor on the main board is pre-adressed and cannot
be changed.

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.
