Specifications
Specifications
Compact and lightweight design
With a low weight of just 21 kg, this ventilation unit can be installed quickly and safely by a single installer. Its space-saving footprint makes the DucoBox Energy Comfort perfectly suited for small plant rooms and confined technical areas.
Software-controlled left/right configuration
The unit is designed for maximum installation flexibility. Left- or right-hand airflow orientation is adjusted entirely via software, eliminating the need for mechanical modifications. This is made possible by an innovative patented double bypass system.
Automatic calibration
Using constant pressure calibration technology, the AUTO calibration function reduces commissioning time by up to 50%. In real-world installations, this can translate into lower labour costs and faster system setup.
High energy efficiency
Advanced dynamic air filtration ensures consistently high heat recovery efficiency. When combined with optional intelligent demand control based on CO₂ and humidity sensors, the system delivers excellent indoor air quality while minimising energy consumption.
Smart copy function for fast commissioning
An integrated software-level copy feature allows installers to duplicate settings and parameters from one unit to another. This is especially valuable for multi-unit or repeated housing projects, ensuring consistent performance and significantly reducing setup time.

Compact external 2-zone control
The external 2-zone control system divides the home into day and night zones, allowing ventilation to be managed intelligently based on how the space is used.
Ventilation demand is continuously regulated using CO₂ and humidity sensors, ensuring fresh air is supplied only where and when it is required, and always in the correct volume. This zonal approach maximises energy efficiency while significantly improving both acoustic and thermal comfort.
External multi-zone valve for DucoBox Energy Comfort
The external multi-zone valve enhances zonal ventilation performance and offers the following key advantages:
1) Space-saving installation
Multi-zone valves are fitted directly into supply ducts (Ø125 or Ø160) and require just 78 mm of installation depth. They can be positioned anywhere within the ductwork, giving installers complete freedom to optimise placement based on accessibility and installation convenience.
2) Significant energy reduction
Zonal ventilation targets only the rooms that are occupied, rather than ventilating the entire home continuously. This intelligent airflow management can reduce energy consumption by up to 40%, lowering the load on both the ventilation unit and the heating system.
3) Quieter system operation
By reducing fan speed and motor activity, the system operates with noticeably lower noise levels—up to 30% quieter—enhancing overall indoor comfort.
4) Improved thermal comfort
The unique comfort temperature control allows individual temperature settings per zone. For example, living areas can be set to 21.5°C, while bedrooms remain at 18°C, creating a balanced and personalised indoor climate with superior thermal comfort.
