2. Application description
2.1 Mode of operation and areas of application
The KNX-LUNOS-Control4 module enables control of the decentralized ventilation devices of the
company Lunos (www.lunos.de) via the KNX-BUS.
Ventilation devices of the series E2 , Ego and NEXXT with heat recovery
Ventilation devices Silvento (FK, EC, 30/60/100), Ra 15-60, ACM-Modul or 0..12V As pure
exhaust air fans
Up to 4 ventilation devices can be operated with a module. Several modules can be networked via the
KNX bus to enable a coordinated operation in a master/slave network. The supply voltage of the fans E²
and Ego is generated in the module from an external auxiliary voltage.
Direct control of the ventilation devices can be carried out via the existing button / switch inputs. The
KNX module KNX-LUNOS2-Control4 is commissioned via the ETS in connection with the associated
Application program. The devices are unprogrammed in the delivery state. All functions are
parameterized and programmed via the ETS.
2.2 Functions
Voltage supply of the fans from low voltage 24..32VDC
Operation of 2 pairs of fans (4 fans) with one module
Several modules cascadable ( Master/Slave -operation )
Control of the fan stages and directions as well as heat recovery
Manual setting of the fan stages via button / switch inputs or KNX telegrams
Control of fan speed and heat recovery depending on:
Air humidity relative (inside) for moisture removal
Air humidity absolutely (inside / outside) for basement drying
Temperature (inside) for building protection
Temperature (inside / outside) to optimize heat recovery
Temperature (inside / outside / should) for heating / cooling support
CO2 concentration
The values temperature (inside / outside), humidity and CO2 concentration must be provided
from other KNX components (For example SK10-THC for the outdoor area , SK30-THC-CO2 for
indoor use).
Supply air operation to support separate exhaust air devices
Exhaust air operation (in combination and individually)
Compensation of line resistances (in the event of large line lengths) possible
Operation in HVAC mode according to KNX standard
Operating modes:
Comfort mode ( HVAC )
