OPERATION Intelligent humidity control Nilan’s humidity control automatically adapts to the needs of inhabitants or the building itself. Immediately change in % of RH The intelligent CTS400 / CTS602 control unit does not require a set air humidity level (RH) to manage the air exchange. Using the integrated humidity sensor, the control unit calculates the average humidity over the past 24 hours and regulates the air flow accordingly. Consequently the unit’s efficiency is based on actual instead of theoretical air humidity levels. Forced ventilation Reduced ventilation Normal ventilation Automatically...
