SMART HOME AND AUTOMATION
Climate is part of the whole system.
BACnet, Modbus and KNX gateways connect compatible equipment to building management. We coordinate capabilities with your designer.
How it connects to the building
The gateway sends commands and equipment status to the building management system: on/off, mode, temperature, fan speed and faults. BACnet, Modbus or KNX is selected for the automation project; connection capacity depends on the gateway.
We select the protocol, gateway capacity and required functions together with the automation designer. Catalog: pages 184–185.
EVERY DETAIL CONSIDERED
Complete your system.
Select the features you need. We will include them in your enquiry and check compatibility.
ComfortHi-Motion
Detects occupant activity and helps manage comfort without constant manual adjustments.
Features and compatibility
How it works
A separate sensor mounts on the wall or ceiling. The system can switch the unit off when the room is empty and adjust temperature and airflow as activity changes.
- Ceiling coverage up to 30 m² according to the catalog
- Wall or ceiling mounting
- Automatic switch-off when unoccupied
Where it helps
Meeting rooms, offices and other spaces used intermittently.
Compatibility
Listed for all indoor unit types in the catalog. Functions and wiring are checked for the selected configuration. Sold as a separate option.
Catalog pages 33, 187
ComfortMotion sensor for cassette units
Fits into the cassette panel and adjusts air delivery according to occupancy.
Features and compatibility
How it works
Switches the unit on or off as people arrive or leave. Supports airflow toward or away from occupants and temperature adjustment based on occupancy.
- Installation in the decorative panel
- Direct airflow or draft avoidance
- Automatic occupancy-based control
Where it helps
Offices and public spaces with cassette units.
Compatibility
Four-way cassettes and mini-cassettes use different sensors. Selected together with a compatible panel.
Catalog pages 33, 187
ComfortHumidity sensor
Adds humidity monitoring and automatic dehumidification.
Features and compatibility
How it works
Provides humidity readings to the system. The catalog specifies a 35–90% setting range for compatible configurations. This is a dehumidification function; the sensor itself does not humidify the air.
- Relative humidity monitoring
- Automatic dehumidification
- 35–90% setting range for compatible systems
Where it helps
Spaces where controlling humidity is as important as temperature.
Compatibility
Listed for four-way cassettes, mini-cassettes, console, ceiling ducted and floor units. Function availability depends on the configuration.
Catalog pages 37, 187
AirFilters and filter units
Filtration matched to the indoor unit and ventilation requirements.
Features and compatibility
How it works
The catalog includes G4 cassette filters, a G1 filter for specified ducted and fresh-air models, and separate filter boxes with a G4 + F7 + F9 combination.
- Replacement filters for cassette units
- Separate filter boxes
- Filter grade and size matched to the model
Where it helps
Projects with additional supply-air filtration requirements.
Compatibility
Filters are not universal. We check fitting dimensions and allowable air-path resistance. G1/G4/F7/F9 are the designations used in the catalog.
Catalog pages 187
AirFresh-air adapter
Connects an outdoor air supply to a compatible cassette.
Features and compatibility
How it works
The adapter connects the fresh-air duct to the indoor unit. Fresh-air volume and supply-system components are determined by the ventilation design.
- Fresh-air duct connection
- Integration with a cassette system
- Selected as part of the ventilation design
Where it helps
Spaces that need an organized fresh-air supply alongside air conditioning.
Compatibility
Listed for four-way cassettes and mini-cassettes. The adapter is not a fan or a complete fresh-air handling unit.
Catalog pages 37, 187
AirAir purification kit
An optional kit for the indoor units specified in the catalog.
Features and compatibility
How it works
The catalog lists two kit variants with a 220–240 V, 50/60 Hz power supply. Selection depends on the indoor unit type.
- Variant for cassettes and mini-cassettes
- Variant for ducted and console units
- Connected during system installation
Where it helps
When selecting additional air-treatment functions for a compatible system.
Compatibility
Cassette and ducted/console units use different kits. Cleaning performance and components must be confirmed from the selected product documentation.
Catalog pages 188
InstallationDrain pump
Pumps condensate away when gravity drainage is unsuitable.
Features and compatibility
How it works
The pump forms part of the condensate drainage system. Selection depends on the indoor unit, lift height and drain-pipe route.
- Condensate removal along the designed route
- Several variants for different units
- Power supply and lift-height checks
Where it helps
Concealed installations and spaces where the required drainage slope cannot be provided.
Compatibility
The catalog lists 220–240 V and 208–230 V pumps. One variant is intended for all indoor unit types except wall-mounted units; the others have specific compatibility lists.
Catalog pages 188

- Three-dimensional air distribution
- Temperature and humidity display
- Three sizes for different configurations
Where it helps
Interiors with a concealed ducted unit where a neat visible panel is required.
Compatibility
The table specifies slim AC/DC ducted units. Catalog panel sizes are 180 × 740 × 70, 180 × 950 × 70 and 180 × 1220 × 70 mm. Selection must match the model.
Catalog pages 144, 188
ProtectionR32 leak monitoring
