The QCR11-MOD-LRA Series LoraWan Controllers have been designed to be wall mounted universal temperature and air quality (CO2) controllers in room spaces. The controllers are suitable for a wide range of applications and have pre-defined application logic that covers most room control heating and cooling systems such as fan coil units, chilled ceilings, zone heating, variable air volume dampers etc. LoraWan allows the controllers can connect wirelessly to the IoT or the Building Management Systems.

The QCR11 Series LoraWan controllers can have additional VOC (Volatile Organic Compounds), Relative Humidity or PIR Occupancy sensors. Additional VOC, dehumidity/humidity control loops expand the multi-functional controller further.

The  room controllers are supplied with an attractive colour touchscreen display with glass front that provides intuitive user interface. The display colour scheme can be tailored using different skin colours. The controllers are mounted on the wall surface directly or to standard wall mounting boxes. The controllers have additional built-in Modbus RS485 communication that allow further local interaction to the BMS systems (Building Management Systems). 

The QCR11 LoraWan controllers can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. The QCR11 controllers are available in white and black (in addition to the touchscreen colour skins). For ease of commissioning the controller address can be set from the bit switch or from the touchscreen.
