| `tec_u_meas` | Volts | Measurement of the voltage across the TEC |
| `pid_output` | Amperes | PID control output |
Note: With Thermostat v2 and below, the voltage and current readouts `i_tec` and `tec_i` are disabled and null due to faulty hardware that introduces a lot of noise in the signal.
## 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](./doc/PID%20tuning.md).
