Instructions for switching thermocouples can be found below...
Yes, this is included in the baseline configuration. The switch from chamber to pot control is initiated by a button press on the screen. However, the user can do that almost immediately, because there are rate limiting features to make sure that the pot temperature doesn’t run away due to significantly higher chamber temps as the salt gets up to molten.
When operating with the immersion thermocouple active, the controller will rate limit the chamber temp such that the pot temp doesn’t avalanche. This ultimately helps to prevent any overshoot and provides a more stable control solution.
