How to use

Install the fan insert into the ductwork or housing according to the ventilation layout and local building standards, ensuring correct airflow direction and secure mounting. Connect electrical supply and control wiring as specified by the system documentation and local regulations. Use the ELS NFC control interface to commission the unit and adjust airflow settings: bring a compatible NFC device close to the control area and follow on-screen prompts or the manufacturer's setup sequence to select operating modes and fine-tune performance. Verify airtight connections and test the system for proper airflow, noise level, and control responsiveness before regular operation.

Recommendations

For consistent performance, select installation positions that minimize sharp duct bends and obstructions. Observe manufacturer guidance for electrical connection and earthing. Periodically inspect the fan insert and surrounding ductwork for dust buildup or blockages and clean according to maintenance instructions to preserve airflow and reduce noise. When integrating into systems serving multiple rooms, balance airflow settings to ensure even ventilation and avoid over-ventilating or under-ventilating individual spaces.
