The QCR13 Slimline Series Modbus Controllers have been designed to be wall mounted in a junction box and are suitable for a wide range of fan coil unit applications. The controllers have built-in temperature measurement, integrated CO2 air qulaity measurement and 3 x 230V rated relays for 3-speed fan control. With integrated CO2 measurement the air quality can be controlled energy efficiently. With LoraWan option the controllers can connect wirelessly to the IoT or the Building Management Systems.
 
The QCR13 Series Modbus controllers can have additional VOC (Volatile Organic Compounds), Relative Humidity or PIR Occupancy sensors. Additional VOC, dehumidity/humidity control loops expand this FCU controller further to more advanced applications.
 
With the TS-Option 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 to standard wall mounting boxes, and offer slimline 13.8mm depth from the wall surface. The controllers have built-in Modbus RTU communication that allow interaction to the BMS systems (Building Management Systems). Optional Bluetooth wireless interface provides connection to Smart Phone App interface (iOS).
 
The QCR13 Modbus controllers can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. The QCR13 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 touchscreen.
