As far as I can acertain, providing KEY <code>run</code> is set to 1 (automatic) the PID will automatically switch the solid state relay output on and off to allow temperature regulation of the heating device; a slow cooker in my case. | As far as I can acertain, providing KEY <code>run</code> is set to 1 (automatic) the PID will automatically switch the solid state relay output on and off to allow temperature regulation of the heating device; a slow cooker in my case. | ||

The thermocouple that came with the PID unit was unsuitable as it was not waterproof and my chosen replacement was wildly inaccurate, probably because its operating range was so large (-100°C to 1250°C Probe 1M). Now to find a more accurate waterproof thermocouple. | The thermocouple that came with the PID unit was unsuitable as it was not waterproof and my chosen replacement was wildly inaccurate, probably because its operating range was so large (-100°C to 1250°C Probe 1M).
