E05 error code. Not sure if you all have gotten help yet, but the mastertemp E05 error code is related to the stack flue sensor and the NT is, like posted, the flame sensor code. The NT will give this code for other reasons also, such as low gas pressure, blocked orfices or inadequate air flow.

What causes a Pentair mastertemp 400 error code E05?

I see more E05 errors that are due to things like a sooted exchanger (fuel delivery, venting), scaled up exchanger (water side), or a low water flow. I see those problems a lot more than a sensor that has gone bad. I could even buy that continued high temps could eventually cause a SFS to fail.

What should stack flue temp be before shutting down heater?

The SFS will let the heater stack temp to run up to 480 degrees before it will shut the heater down. In the case of a sooted exchanger, the stack flue temp would rise slowly over time (weeks/ months) subjecting the sensor to extended over temp conditions.
