PeltierController

Author: Bram Laurens
Title: Peltier Controller
Date: 2025

This is a simple self-contained Windows application to control a peltier module connected to a Roboteq VRS1460 motor controller.

Instructions:

  1. Connect controller to USB.
  2. Power on the driver

BEFORE CONTINUING: Double check that the fan is properly connected to the power supply on the Roboteq driver. Also confirm that the fan is spinning! Powering the peltier module without the fan spinning can result in heat damage!

  1. Open the program "PeltierController.exe", you might get a Windows SmartScreen warning, click "More Information" > then run anyway.
  2. Select the correct COM port from the drop down menu at the bottom, you might need to refresh the list.

Auto mode:

  1. Click "Automatic Control"
  2. Enter a temperature in Celsius next to the "Set temperature button"
  3. Click the "Set temperature button"

Manual mode:

  1. Click "Manual control"
  2. Select cooling or heating mode
  3. Enter a PWM value between 0 and 100 for cooling and 0 and 40 for heating in the text field, next to the PWM button. The unit is duty cycle %.
  4. CLick "Set PWM Duty cycle"
  5. Your module should now heat or cool!
  6. Click reset to turn module off (set PWM duty cycle to 0)

Note: it takes 10 minutes for the module to stabilize temperature once given a PWM duty cycle in manual mode

No additional programs required.
