The door contact magnetic switch is used for the automatic, demand-based control of air curtains in automatic mode. When the door opens, it automatically activates the air curtain and switches the unit to the previously selected power or fan settings. In conjunction with the control system, the air curtain and heating operations can thus be controlled via the door contact.

Thanks to this automatic control, the air curtain operates only when it is actually needed. This improves user convenience, reduces unnecessary operating time, and promotes energy-efficient operation in the entryway. At the same time, the integration with the preselected settings ensures that the desired airflow is immediately available when the door opens.

The door contact magnetic switch is particularly well-suited for entryways with frequent door openings, such as in retail, office, or commercial buildings. It enhances the air curtain control system with a practical automatic function and helps minimize drafts while effectively shielding the interior from cold or warm outside air.
