The TCR83 Series Controllers are ceiling mounted fan coil unit controllers for flexible control of room spaces. They are ideal for applications where 3-speed fan control is required (3 x 240V 3A fan relays provided). The controllers can be connected to a TDR20/QDR20 room display panel using the USB-C cable, making installation and connection simple. The controller's built-in universal inputs can be used with cable sensors. The room interface panels have temperature measurement, setpoint, fan speed, boost function and operating mode selection (configurable). In addition the room interface panels can have optional humidity, VOC, CO2 and occupancy measurements.

The TCR83 controllers have flexible control logic configuration and are suitable for wide variety of control applications. Additional functionality is provided making them also suitable for small Air Handling Units. The controllers have built-in Modbus RS485 communication that allow interaction to the BMS systems (Building Management Systems). Optional Bluetooth wireless interface provides connection to Smart Phone App interface (iOS).

The TCR83 Series Modbus controllers can be configured using Windows Device Configuration Tool (connected wirelessly via Bluetooth, or using USB-SERIAL isolated serial cable) or using SmartPhone app (iOS). The controllers have IP65 rated enclosure with cable glands, and are available with 24V or 230V power supply. Ample space is provide for wiring. The wiring connectors are pluggable, and wires can be inserted fast using push technology terminal blocks.
