The TCR4/QCR4 Series Controllers have been designed to be wall mounted temperature and air quality controllers in room spaces.  The controllers have built-in temperature and CO2 measurement. Optional occupancy sensor with 2-button version only. 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 temperature and CO2 measurement, and the controller operating status. The user can adjust the setpoint and fan speed 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 RTU or BACnet MS/TP communication that allow interaction to the BMS systems.
 
The TCR04/QCR04 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.
