Below are our recommendations for setting up the TC100 controller


Switch the temperature scale from Celsius to Fahrenheit

  1. Hold “Set” for a few seconds until “tS” appears
  2. Hit set to cycle through option until “CF” appears
  3. Use the arrows to switch from C to F then hold “Set” for a few seconds


Change the temperature differential value

The default differential setting is 3 degrees. This means that if your set temperature is 60F, it will not turn on the cooling pump or heating until the actual temp is 63F or 57F respectively. We recommend a temperature differential value of 1 to maintain your set temp as best as possible.

 

  1. Hold “Set” for a few seconds until “tS” appears
  2. Hit set to cycle through options until “HD” appears.
  3. Use the arrows to adjust the value to 1. The heating differential is now set to 1
  4. Hit set to cycle through options until “CD” appears.
  5. Use the arrows to adjust the value to 1. The cooling differential is now set to 1
  6. Hold “Set” for a few seconds to return to the temperature display

 

Change the Set temperature

  1. Hold “Set” for a few seconds until “tS” appears
  2. Use the arrows to change the temperature you want your batch to be at.

Temperature Control Range Setting (TS, HD, CD)

When the controller is working normally, the LED displays the current measured temperature, and automatically switches between refrigeration and heating modes as needed.

When the measured temperature is above your set temperature by at least CD (cooling differential value) degrees, the system enters refrigeration status. The cool indicator light turns on, and power is provided to the Cooling outlet (when the cool indicator light is flickering, it is waiting for compressor delay protection time to count down). When the measured temperature reaches your set temperature, the cool indicator light turns off, and the refrigeration relay shuts off. When the measured temperature is below your set temperature by at least HD (heating differential value) degrees, the system enters heating status. The heat indicator light turns on, and power is provided to the Heating outlet. When the measured temperature reaches your set temperature, the heat indicator light tuns off, and the heating relay shuts off. For example, with TS= 25 °C, CD= 2 °C , and HD= 3 °C, when measured temperature is higher or equal to 27 °C (TS+CD), the system enters refrigeration status; when temperature drops to 25 °C (TS), refrigeration stops. And when measured temperature is lower or equal to 22 °C (TS-HD), the system enters heating status; when the temperature increases to 25 °C (TS), heating stops.

 

Alarm High/Low Limit Setting (AH, AL)

When measured temperature is higher or equal to AH, high temperature alarm will be triggered and will beep until the temperature is lower than AH or any key is pressed. When measured temperature is lower or equal to AL, low temperature alarm will be triggered and will beep until the temperature is higher than AL or any key is pressed

 

Compressor Delay (PT)

If the measured temperature is higher than the set temperature (TS) by (CD) degrees, the equipment normally enters refrigeration mode. To avoid too frequent cycling of the attached refrigeration unit compressor, Compressor Delay can be used. Setting Compressor Delay (PT) is the time in minutes you want to wait between compressor cycles. When your last refrigeration mode ends, a timer starts counting, and the unit won’t power the refrigeration relay until the timer exceeds (PT) minutes. The cooling light will blink until this time has passed, and then it will enter refrigeration mode normally.

 

Temperature Calibration (CA)

If the temperature sensor has an error in measuring the actual temperature, you can use the temperature calibration function to align the measured temperature and actual temperature. The value you put into (CA) is added to the measured temperature before reporting the measured value. (CA) Can be a positive value, 0, or a negative value.

 

Display in Fahrenheit or Centigrade (CF)

You can select to display in Fahrenheit or Centigrade. Default setting is to display with Centigrade. To display with Fahrenheit temperature value, set CF value to F. Attention: When CF value is changed, all the settings will be reset to factory default settings
