Siemens DDC 540-865EN TEC Variable Air Volume Heat Modulation

Description

The Siemens DDC 540-865EN TEC VAV Controller is a direct digital control device designed for pressure-independent variable air volume (VAV) terminal units. It regulates airflow and room temperature by processing sensor inputs and controlling VAV dampers and heating equipment. Its 0–10 V analog output provides precise modulation of reheat, while CO₂ monitoring helps adjust ventilation according to indoor air-quality conditions. The controller is commonly used with VAV boxes, electric reheat, and hot-water heating systems in commercial HVAC applications. Benefits include improved comfort, accurate temperature control, better ventilation, energy efficiency, and reduced maintenance requirements.

For an efficient and reliable HVAC system, the Siemens DDC TEC Variable Air Volume Heat Modulation is a great choice for optimal system performance.
