How to Set Temperature Range Control with TCN5 Series Controller (45–50°C Example)

I. Introduction

In temperature-sensitive applications such as incubators, heating chambers, or brewing systems, maintaining a precise temperature within a set range is essential. In this guide, we demonstrate how to configure the TCN5 Series Temperature Controller to work between 45°C and 50°C, using its built-in hysteresis control function.

This video tutorial showcases how to achieve:

• Output ON when the temperature drops to or below 45°C
  
• Output OFF when the temperature reaches or exceeds 50°C
  

This type of control is perfect for avoiding frequent on/off switching and maintaining system stability.

Watch how the TCN5 controller is configured to handle this logic using Hysteresis Control Mode:

III. Step-by-Step Configuration

1. Enter Parameter Setting Mode:

• Press and hold the SET key for 3 seconds to enter the parameter menu.
  

2. Set Control Mode to ON/OFF (PID:OFF):

• Find the parameter PID (control method), and set it to OFF for ON/OFF control.
  

3. Set the Desired Set Value (SV):

• Set SV = 50.0°C, which is the upper limit (cut-off point).
  

4. Set Hysteresis (oH) to 5.0°C:

• This will create a lower limit of 50 - 5 = 45°C.
  
• So, heating turns ON at 45°C, and OFF at 50°C.
  

5. Ensure Output is Set to Heating Mode:

• Output type should be configured to Heating (reverse), so output activates when temperature is below SV.

V. Applications

This control method is ideal for:

• Heating incubators
  
• Small ovens
  
• DIY electronics temperature projects
  
• Home brewing and fermentation
