Description
• Multi controller QTRL (CA-L3) is a programmable unit for function management within in the ControlAir system for demand-controlled ventilation, e.g. BAS or SYS for comfort ventilation and uLAB for laboratory ventilation.
• The multi-controller is usually delivered factory assembled, alternatively integrated into the product, but can in some cases be delivered loose for mounting on cable trays, walls or ceilings.
• The functionality depends on the installed software version.
• Through multiple inputs and outputs, the device is well suited for everything from standardized applications to customized demand control scenarios in projects with very specific requirements.
• Built-in economy function uses presence sensors to achieve energy savings at low occupancy or when the facilities are unoccupied.
• Uses Modbus-RTU as communication protocol.
• The unit can be delivered in several different enclosures or integrated into the product, depending on the product type and application.
• For products where the controller is integrated, there are also options for integrated temperature, humidity and occupancy detection.
• Available as wall-mounted version.
• All products used with the controller are connected either via a terminal on the board or via the device's communication bus. This enables the connection of external sensors, e.g. occupance, temperature and CO₂ detectors as well as window switches.
• We offer a range of accessories for both room and system applications, e.g. presence sensor with 360° detection.
