Xzone

Flexible temperature control for multiple zones - ideal for buildings with diverse temperature demands.

Why should you activate it?

In many buildings, different zones may experience distinct temperature loads due to their location, usage or exposure. Without zone control, you could end up either overheating one area or overcooling another, wasting energy and compromising comfort. 

The Xzone function addresses this by enabling independent temperature control for a secondary zone, ensuring both comfort and energy efficiency throughout the building. This is particularly valuable for perimeter zones or areas with unique heating or cooling demands. Xzone functionality is therefore ideal for areas exposed to varying sun loads, such as workshops or offices, where separate temperature control is needed for optimal comfort and efficiency.

Main benefits

Xzone enables your GOLD air handling unit to manage one extra temperature zone, independently from the main zone. It delivers flexibility and efficiency. It ensures comfort in spaces with different loads, reduces energy waste, and avoids costly over-dimensioning. Perfect for offices with sun-exposed facades, industrial sites with mixed processes, or any building where one size doesn’t fit all.

Key benefits include:

  • Enhanced Comfort: Allows precise temperature control in areas with unique heating or cooling needs, ensuring optimal comfort for occupants in every part of the building.
  • Energy Efficiency: By targeting heating and cooling only where it is needed, Xzone helps reduce unnecessary energy consumption and operational costs.
  • Flexibility: Supports different temperature control strategies (supply air, extract air, or room temperature) for the extra zone, making it adaptable to a wide range of building layouts and requirements.
  • Independent Operation: The extra zone operates separately from the main zone, so adjustments in one area do not affect the other—ideal for buildings with diverse usage patterns.

How does it work?

Xzone uses an additional control box and standard heating and/or cooling coils. It regulates supply air temperature for the extra zone based on its own sensor readings, while the main zone continues with its own settings. Both zones share the same airflow but operate with separate temperature control logic.

This is how it works:

  • The Xzone for heating and Xzone for cooling must each be activated separately. The type of control signal for the heating and cooling function respectively must be selected individually.
  • Temperature control for the Xzone operates completely separated from the temperature control of the main zone.
  • If an air heater for re-heat with frost guard is selected for the extra zone, the heat retention function will operate completely separately. The heat retention and alarm limit values preset at service level are individual for the extra zone and the main zone.
  • The cooling min. flow function applies to the flow from the air handling unit, not the flow for each zone.
  • When the total flow reaches below the preset value, cooling will be blocked in both zones
