DIY Temperature Controller

Posted by on January 16, 2014

In case you missed the meeting when we demonstrated just how easy it is to build your own temperature controller you’re in luck!  Dual stage means heat and cool- so you can control fermentation chambers, heat wraps/ pads, and a host of other applications where you need to turn off/on components based on temperature.

You can download a PDF of the below instructions HERE

THIS is a good video showing just how easy it is to build (many more available on YouTube)

This controller is great for fermentation

Wiring a Dual Stage STC 1000stc

You will need:

  • STC 1000 controller 110v dual stage
  • Power outlet
  • Power cord (three wire)
  • Extra wire
  • Enclosure / cover

Be sure to break off tab on outlet’s hot side, do not break off tab on neutral side.

Controller settings: (press and hold (S) button until display flashes- be sure to hit Power (P) to save settings)

  • F1- Target Temp (in Celsius)
  • F2- Temperature variation before controller turns on (default 0.3 C)
  • F3- Compressor delay- Amount of time before controller will turn on again. This is so the power doesn’t shut on/ off continually with small temperature fluctuations (helps save Fridge/ freezer compressors)
  • F4- Temperature calibration
