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.

Why does my Pentair pool not show the exhaust temp?
“If you hold down pool on button it displays the exhaust temp. – mine was showing 80 and then flashing 40. Obviously something wrong. There is a sensor on the exhaust that looks like a bolt with 2 wires coming out of it – it’s the stack flue sensor. I took it off, cleaned the terminals, screwed the sensor back in and reattached the wire terminals.
How big is a Pentair mastertemp heater meter?
This meter fed not only the 1.5″ line to the 400k btu Mastertemp heater, but a 1.5″ line into the newly remodeled house. I recommended calling the gas company to change out the meter, which they do for FREE.
