## PID Tuning
The thermostat implements a PID control loop for each of the TEC channels, more details on setting up the PID control loop can be found [here](./documentation/PID%20tuning.md).

# PID Tuning
## Note on hardware setup
When using a TEC module with the Thermostat, the Thermostat expects the thermal load (where the thermistor is connected) to heat up when a positive current flow from the TEC + terminal, through the TEC, to the TEC - terminal, and vice versa.
## Real time plot
When tuning Thermostat PID parameters, it is helpful to view the temperature, PID output and other data in the form of a real time graph.
