P-M406The Error says Sensor Short - I guess it thinks the pool is hot enough and doesn't need to turn on?

If you have a sensor short then you need to replace the temp sensor/thermistor. Do you have the manual?

Ok, on page 50, the parts list the sensor is called out as item # 5C. It's location depends on where you have a plastic or metal header
