QCR02 BACnet CO2 and Temperature Controller Wiring Diagram

The TCR02/QCR02 Series Slimline Controllers have been designed to be wall mounted temperature controllers in room spaces. The controllers can have 2 or 3 tactile push buttons with third button printing options for fan, boost and operating mode.  Also optional occupancy sensor with 2-button version. 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 etc.
 
The room controllers have colour LCD screen indicating the current measurement and controller operating status. The user can adjust the setpoint and fan speed/boost/operating mode through the push buttons. The controllers are mounted on the wall surface directly or to standard wall mounting boxes. The controllers have built-in Modbus RS485 communication that allow interaction to the BMS systems.
 
The TCR02/QCR02 Modbus controllers can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. For ease of commissioning the controller address can be set from the bit switch or from the touchscreen.
