Control module for automation expansion Expansion2 001B0005

Expanding Control Capabilities for Heat Recovery

The Expansion2 module is an advanced solution that significantly enhances the functionality of AirPack4 and AirPack Home ventilation control units. It enables integration with a wide range of peripheral devices, allowing the creation of a comprehensive, automated ventilation system tailored to individual needs. This is not merely an extension module—it is the key to full control over comfort and air quality within the building.

Universal System Integration

Thanks to the Expansion2 module, it is possible to connect multiple devices, resulting in greater flexibility and user convenience. It supports integration with:

• Duct heaters—both water-based and electric—providing additional heating during colder periods.
• Duct coolers—for comfort during hot summer months.
• Ground heat exchangers (GWC)—optimizing the use of geothermal energy.
• Intake and exhaust dampers—precisely regulating air flow.
• Range hood switches, fire alarm systems, security alarms, and fireplaces—automating ventilation scenarios based on real-time conditions.
• Air intake temperature sensor—for precise monitoring of air parameters.

This versatile tool empowers both installers and end users.

Design and Practical Application

The Expansion2 module is a standalone device that communicates with the ventilation unit via a dedicated communication cable. Installation is simple and intuitive, while the robust housing ensures protection against mechanical damage and electromagnetic interference. As a result, the module is reliable and resistant to indoor operating conditions.

A signal from a fire alarm or security system enables automatic shutdown of the heat recovery unit in case of emergency, enhancing occupant safety. The ability to connect an air intake temperature sensor allows precise adjustment of the heat recovery unit’s operating parameters to current weather conditions, ensuring optimal comfort and energy efficiency. Control of damper actuators enables regulation of the volume of fresh air entering the rooms, improving air quality and enabling effective energy management.
