Table 1 Digital universal inputs available for selection
User modes Activation of specific user modes.
Central Vacuum Cleaner
Activation of Central vacuum cleaner function.
Cooker hood function
Activation of Cooker Hood function.
External Stop
Air handling unit is stopped by an external command.
Extra controller Alarm
Indication about an alarm in external controller. Used for Extra Heater/Cooler/
Preheater.
Change-over feedback
Used with Change-over systems. Indicate if the temperature of heating/cooling fluid
in the system is right.
Fire Alarm
Air handling unit is stopped due to fire. Can be used with smoke alarms or similar.
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.
Digital inputs are restricted by signal type and physical number of connections. An input function is only allowed to be
used once.
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.
Already used and configured input signal type is greyed out and not available for selection. However some user func-
tions related to configuration of digital input (AWAY, CROWDED, FIREPLACE, HOLIDAY or REFRESH) have several possi-
ble activation points, via HMI/APP/Wireless/Modbus (BMS).
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.
PDM (pulse density modulation) input for relative humidity (RH) sensor on the main board is pre-adressed and cannot
be changed.
