Find the current firmware version for your SCS Controller
If you are unsure what version of firmware is installed on an SCS Controller, you can find it either by using Field app or by power cycling the cooler.
Either:

- Open to Field app and connect to the SCS Controller.
- Open the main menu then tap SCS INFO.
- The current firmware version will be listed at the top of the page (See image on right).
- "SCS"
- The current Firmware Version. This is a 6-digit number with the first 3 digits on screen for 2 seconds, then the remaining 3 digits for 2 seconds.
- Outputs connected to the Controller - e.g.“CoP” (Compressor), “FAn” (Fan), “LIt” (Lights) as it self-tests the outputs.
- Current temperature
