The TC3B Series provides temperature, alarm, and optional defrost cycle management. The TC3B Series facilitates defrost management for hot gas or electric heat defrost, with time-based or temperature-based defrost termination. The series can replace a temperature control, a digital temperature readout, and a defrost timer. Some TC3B models can also control an evaporator fan and lighting. The TC3B Series also includes a model with pulse-width modulation (PWM) output to drive a variable speed compressor.

The TC Series controllers are a range of energy efficient, microprocessor-based, multifunctional, programmable temperature controls for self-contained refrigeration systems that operate with both on-off switches and variable speed compressors. Depending on the model you choose, TC Series controllers can also manage alarms, active or passive defrost cycles, evaporator fan functions, and case lighting.

A large, red LED display is standard for all TC Series controllers. If you order more than a minimum quantity, you can order controllers with white, blue, or green LED displays. The TC Series are panel-mount controllers. They use EVTPN temperature sensors so that you can remotely mount the display unit. All TC Series controllers have a variety of optional inputs and output relays to perform compressor, defrost, evaporator fan, lighting control, and alarm management control. TC Series controllers consist of three groups of controllers: TC3B, TC3, and TC3X

Capacitive touch keys	The patented capacitive touch UI provides the controller with a modern and elegant design. You can easily clean the controller’s flat front surface. The capacitive touch keys provide reliable, long-life operation and eliminate a common point of failure with electromechanical keys that many competitive devices contain.
Variable speed compressor	The TC3B Series includes a model that drives Tecumseh, Embraco, and Secop variable speed compressors.
IP65 rating	The capacitive touch UI achieves an IP65 rating. The water resistant UI minimizes the risk of damage due to water and moisture entering the controller.
Adaptive defrost	The controller monitors the heat transfer performance of the evaporator coil to start defrost at the time that the environment requires. If you optimize the defrost cycle based on the system demand, you increase energy efficiency, along with the quality and shelf life of refrigerated products.
Compressor protection	Active power line monitoring ensures that the compressor only cycles on at the optimal point.
TC3KEY programming key	Use the TC3KEY programming key to automatically program devices. You can store and replicate programmed device configurations on another TC3 device. Integrated LEDs indicate progress and completion status.
Reduced depth option	TC3X series controllers are ideal for applications that require a reduced panel-mount depth of 39.5 mm (1 9/16 in.).
Optional RS485 communications adapter	Some TC3 models are compatible with optional TTL to RS485 serial adapters for Modbus RS485 communications. You can use DIP switches or software parameters to configure the Modbus address.
Optional communications adapter real-time clock	The TCIF23 model RS485 communications adapter includes a real-time clock. The clock ensures that the controller performs daily defrost schedules at the correct time of day, and stores all logging samples accurately with a time and a date stamp to facilitate accurate Hazard Analysis and Critical Control Point (HACCP) reporting.
Optional color display	The standard TC display is red. If you order more than a minimum quantity, you can order controllers with white, blue, or green LED displays.
