TC3223N5V-000C Johnson Controls Refrigeration Controller

Overview

The Johnson Controls TC3223N5V-000C is a multifunctional, programmable refrigeration controller engineered for self-contained low and medium temperature refrigeration systems. Operating on a 115 VAC power supply, this microprocessor-based panel-mount device coordinates operations between sensors and refrigeration components by providing temperature control, a digital display readout, defrost cycle timing, and defrost termination functions. It features a modern flat front design with capacitive touch keys and built-in TTL Modbus communication capability for integrated network connectivity.

Features

• Patented capacitive touch user interface for a sleek design and long-lasting mechanical life.
• Water-resistant front panel achieving an IP65 rating to minimize moisture damage.
• Adaptive defrost capabilities that monitor evaporator coil performance to execute defrost cycles only when required.
• Active power line monitoring for compressor protection, ensuring startup occurs at the optimal point.
• Support for the optional TC3KEY programming key to replicate and store device configurations easily.
• Compatibility with optional TTL to RS485 adapters for extended Modbus communication networks.

Specifications

• Power Supply: 115 VAC (+10% / -15%), 50/60 Hz, 2 VA maximum.
• Inputs: 2 connections (typically optimized for room temperature and evaporator probe monitoring using EVTPN sensors).
• Outputs: 3 output channels (K1 relay for compressor control, configurable relays for defrost, evaporator fan, and alarms).
• Communication Protocol: TTL Modbus subordinate port.
• Mounting Style: Panel-mount with supplied snap-in brackets.
• Enclosure Protection: IP65 rating on the front surface.
• Operating Temperature: 0°C to 55°C (32°F to 131°F).
• Display Type: 3-digit custom LED display with dedicated function icons.

Applications

• Commercial refrigeration equipment, including self-contained coolers, display cases, counters, and food service islands.
• Low and medium temperature cooling management system networks.
• Centralized building automation systems (BAS) demanding remote monitoring and data logging via Modbus networks.
• HACCP compliance logging and daily scheduled defrost monitoring when integrated with a real-time clock adapter.
