 To set the properties of the transducer (TEC or heater) and thermistor for an individual channel from the Home screen, touch CH X > Settings > Plant.  The menu in <imgref plant> will appear.  Select TEC/Bipolar (as seen) or by touching TEC/Bipolar, select Heater/Unipolar.
-From this screen, it is also possible to set the polarity of the TEC.  Touch Polarity Positive/Polarity Negative to toggle between the two states. The polarity is already set correctly to POSITIVE for use with NTC thermistors.

 The thermistor data has been configured at the factory for a typical NTC thermistor that is 10 kΩ at 25°C.  Only NTC (Negative Thermal Coefficient) thermistors can be used.  You can enter a new Beta value, reference temperature, and resistance value and the Steinhart-Hart constants will be calculated automatically or vice versa.

 ===== Serial API =====
 It is possible to control the SLICE-QTC through serial commands.  Click here to access the [[slice:qt:API|SLICE-QTC API]].
+<WRAP round important 100%>
+Upgrading the SLICE-QTC firmware is not always necessary to use the Serial API. Check your installed firmware version in the settings menu against the most recent firmware version given [[https://github.com/Vescent/SLICE-QTC-Firmware-Upgrade|here]].
