Function
Functions:
Damper
No
No air damper.
Comb.
Two air dampers with a common output.
Supply air
Supply air damper with output.
Extract air
Two dampers with separate outputs.
Extract air fan
Extract air fan (supply air fan is always available and cannot be deactivated).
None
No extract air fan.
Separate
Extract air fan with separate output.
Comb.
Extract air and supply air fans with common output.
Fan regulation
type
Select fan and regulation type.
The supply air fan slave and extract air fan slave settings cannot be used without an activated
extract air fan.
If the extract air fan is set as combined, only the settings Direct and Dir.fro can be used.
The exact number of outputs depends on the number of steps and whether the extract air fan is
activated. The number of inputs/outputs required is doubled if the fan has a separate output.
The sensors that are required, for example pressure sensors, are also activated with this parameter.
Direct
Up to three digital outputs each for direct-drive fans.
Dir.fro
Up to three digital outputs each for frequency-regulated fans with fixed steps.
Fixed freq.
One digital and analogue output each for frequency-regulated fans regulated via modulating
analogue outputs (e.g. St1 = 2 V, St2 = 5 V, St3 = 8 V).
Pressure reg.
One digital and analogue output and one analogue input each for frequency-regulated fans in
pressure-regulated systems.
Flow reg.
One digital and analogue output and one analogue input each for frequency-regulated fans
regulated in flow-regulated systems.
Supply air fan
slave
One digital and analogue output each and three analogue inputs for frequency-regulated fans in
pressure-regulated systems where the supply air fan is driven depending on the extract air fan.
Extract air fan
slave
One digital and analogue output each and three analogue inputs for frequency-regulated fans in
pressure-regulated systems where the extract air fan is driven depending on the supply air fan.
Tmp control
mode
Select the regulation algorithm for temperature regulation
Supply air
Temperature regulation of supply air only.
Room casc.
Cascade regulation of room and supply air temperature.
Extract air casc.
Cascade regulation of extract and supply air temperature.
Room SuWi
Cascade regulation of room and supply air temperature in summer; regulation of supply air
temperature only in winter.
Extract air SuWi
Cascade regulation of extract and supply air temperature in summer; regulation of supply air
temperature only in winter.
Room
Room regulation only.
Extract air
Temperature regulation of extract air only.
Mixing damper
Heat recovery regulation with mixing damper.
No
No mixing damper.
Normal
Mixing damper with output signal 100% for full circulation.
Inverted
Mixing damper with output signal 0% for full circulation.
Heat recovery
Select heat recovery regulation with rotating heat exchanger, plate heat exchanger or water heat
exchanger.
No
No heat recovery.
Rotor
Rotating heat exchanger. One analogue output for regulation of rotating heat exchanger.
Plate
Plate heat exchanger. One analogue output for regulation of regulating air damper.
Water
Water heat exchanger. One analogue output for regulation of the valve.
