CP3 auto fill did not start, looks like thermocouple temperatures were out of range

CP3 auto fill did not start, here are the logs

Starting CP3 fill. TC A error. TC B error. Fill aborted.

Starting CP4 fill. LLCV enabled. LLCV set to manual control. LLCV set to 70% open. Fill completed in 90 seconds. TC A did not register fill. LLCV set back to 35.0% open.

The code looks at the TC-A and TC-B temps before starting, for CP3 if they are below -20C the script will abort.

Looking at CP3 StripTool (attached) it looks like the script ran when the temps were in their low spike.

VAC team are looking into the issue.

CP4 filled normally.
