Regulation Programs
Hexamotion units are available in 5 different regulation programs, available with right or left access depending on airflow direction:
- SEASON – Optimized for temperate climates, adjustable flow rates, summer/winter heat exchanger operation.
- FIRST – Self-regulating with active temperature management for efficient energy consumption.
- PREMIUM CO – FIRST features + changeover water coil for temperatures down to -20°C.
- PREMIUM DXR – FIRST features + changeover R410A coil for temperatures down to -20°C.
- PREMIUM BE – FIRST features + electric heater for temperatures down to -20°C.
Controllability
Hexamotion units offer 6 flow rate modulation options for optimized energy consumption:
- SEASON – Manual fan speed adjustment via potentiometers.
- ECO – Fan speed adjustment via two airflow settings (LS-HS).
- Lobby® – Constant pressure mode with adjustable fan speed.
- Diva® – CO₂-based airflow modulation with sensor integration.
- Mac2® – Constant airflow modulation (except sizes 05 and 08).
- Quattro® – CO₂-based constant airflow modulation (except sizes 05 and 08).

Ductwork Insulation Recommendations
For best performance, we recommend using Metal Spiral Ducting and Fittings. To ensure airtightness and durability:
- Apply duct sealant to male fittings.
- Push components together.
- Seal the joint with aluminum duct sealing tape.
Ducting in cold areas (e.g. loft spaces) must be insulated with at least 25mm thick material with thermal conductivity ≤ 0.04W/(m·K) to prevent condensation. Intake and exhaust ducts should be insulated even if there is no loft space. Bubble wrap insulation is not compliant with building regulations.
Accessories
Complete your ventilation system with a range of compatible controls, sensors, silencers, and valves/diffusers.
