Additionally, the controllers support communication output, allowing users to configure parameters via PC and monitor real-time temperature and output status using the remote display units (TFD series, sold separately).

Key Features

Standard Installation Size

The TF3 Series controllers are built to standard dimensions (W70.3 × H28.2 mm), making them compatible with most refrigeration panels and ensuring a straightforward installation process.

Versatile Compressor Load Capacity

The controllers come with various compressor load capacities, including 5A, 16A, and 20A, to accommodate different load requirements, ensuring optimal performance across diverse applications.

Advanced User-Friendly Functions

• Defrost Sync Function: This feature enables the simultaneous defrosting of up to six controllers, streamlining the defrost process and ensuring consistent operation.
• Real-Time Clock (RTC) Function: The RTC function supports night mode operation and allows for precise, real-time defrost control, enhancing energy efficiency.
• Built-In Alarm Function: Alerts users to specific conditions, helping prevent potential issues before they escalate.

Remote Monitoring Capability

The TF3 Series supports real-time remote monitoring of temperature and output status when paired with the TFD series remote display units (sold separately). This feature enhances operational oversight and allows for quick adjustments as needed.

Communication Options

The controllers are equipped with RS485 communication capabilities using the Modbus RTU protocol. This feature facilitates seamless integration into broader monitoring systems and allows for parameter configuration via the DAQMaster software, which is included with the product.

Robust Protection Structure

The TF3 Series front panel is rated IP65 under the IEC standard, offering strong protection against dust and water, ensuring durability in challenging environments.

Software

DAQMaster

The DAQMaster software is a comprehensive device management program included with the TF3 Series controllers. It allows for easy parameter setting and real-time monitoring of the controllers via a PC, streamlining the configuration process and enhancing operational efficiency.

Product Components

When you purchase a TF3 Series controller, you receive the following components:

• The main TF3 Series product.
• Two mounting brackets.
• An instruction manual for easy setup.
• One NTC sensor (5 kΩ) for accurate temperature sensing.

Communication Interface

RS485 Communication

The TF3 Series controllers utilize the RS485 communication interface with the Modbus RTU protocol. This interface supports asynchronous two-wire half-duplex communication, allowing for the connection of up to 31 devices over a distance of up to 800 meters. The communication speed is adjustable, with options ranging from 2,400 to 38,400 bps, making it adaptable to various system requirements.

Input Types and Ranges

The TF3 Series supports multiple input types, including NTC thermistors (5 kΩ and 10 kΩ) and RTD (Pt100 Ω), providing flexibility in temperature measurement. The display accuracy is maintained within ±1°C at room temperature (23°C ±5°C), ensuring precise temperature control.

Display and Indicators

The TF3 Series controllers are equipped with a 7-segment LED display that clearly shows present values (PV) and set values (SV). The interface includes several indicators for monitoring deviations, compressor status, defrost operation, evaporator-fan output, and auxiliary output, ensuring that users are always informed about the system's status.

Additional Accessories

TFD Series (Sold Separately)

The TFD series remote display units are specifically designed for the TF3 Series controllers, enabling users to monitor real-time temperature and output status remotely.

SCM Series (Sold Separately)

The SCM series communication converters allow for seamless integration of the TF3 Series controllers into different system architectures, expanding their functionality and compatibility.
